A comparative investigation of electrochemical characteristics of two complex systems, viz. Cu|Cu(II), glycine and Cu|Cu(II), maleic acid, was carried out. The equations were obtained for quantitative description of pH-metric and spectrophotometric data, which were used for determination of equilibrium characteristics in Cu(II)-maleic acid solutions. Thermodynamic analysis shows that deep changes are possible in this system resulting in 90 % transform of Cu(II) into Cu(I). The rates of Cu corrosion and Cu2O formation are estimated to be of the same order (nmol cm-2 s-1). Regularities of formal electrochemical kinetics, which account for the mass transport of chemically interacting particles and for step-wise charge transfer process, are suitable for interpretation of voltammetric data of the Cu|Cu(II), glycine system. Kinetic parameters Cu(II) glycinate complex depend on the nature of the supporting electrolyte: the exchange current density decreases and the cathodic charge transfer coefficient increases in the sequence: Li+ - Na+ - K+ - Cs+. To enhance the Cu(I) generation in maleic acid system, the pre-electrolysis procedure was applied. It was found that its effect depends on solution pH. Applied theoretical model describes satisfactorily the steady-state voltammetric characteristics of Cu|Cu(II), maleic acid system, but some contradictory results were obtained in the case of time-dependent processes. Theoretical and experimental problems to be solved are discussed.

Abstract:
Cathodic processes occurring in the solutions containing Cu(II) tartaric complexes have been investigated. The equations accounting for the material balance have been constructed and used for the estimation of distribution of complexes and ligands in the bulk of solution. It was established that dominating particles in acidic media (pH < 3) are: Cu2+ and tartaric complex CuL, tartaric acid LH2 and its anion LH-. Potentials of non-polarized copper electrodes were found to be reversible and to follow Nernst equation. According to the analysis performed, surface oxide Cu2O is not able to form in acidic (pH < 3) media. Cathodic voltammograms obtained for the solutions of different acidity exhibit two characteristic current peaks arising from Cu(II) reduction and hydrogen evaluation. An analysis of voltammetric extrema shows that both processes are irreversible. Based on the regularities of the mass transport of chemically interacting substances, surface distribution of components has been simulated. These date were used for the transformation of experimental voltammograms into normalized Tafel plots. According to their analysis, the rate-controlling step of Cu(II) reduction is the transfer of the first electron onto Cu2+ aqua-complex. The values of kinetic parameters were found to be as follows: the cathodic charge transfer coefficient is equal to 0.33 and the exchange current density is equal to 50 mA cm-2. An analysis of the second current peak leads to the conclusion... [to full text]

Abstract:
Chapter 1 provides an introduction to metalloenzymes and discusses Ni-containing superoxide dismutase (NiSOD), which features Ni-thiolate ligation at the active site, and Cu containing galactose oxidase, which utilises phenoxyl radicals to perform its catalytic function. Studies concerning low molecular weight analogue complexes of each active site are reviewed and their relevance with respect to enzyme structure and function is discussed. Chapter 1 concludes with a description of the aims of this thesis project. Chapter 2 discusses of the preparation of a series of Zn(II), Ni(II) and Cu(II) Schiff-base diphenolate complexes incorporating the four novel pentadentate pro-ligands, [H2tBuLOH], [H2tBuLOCl], [H2tBuLOtBu] and [H2tBuLOOMe]. The different pKa values of the para-substituted arylamines (H, Cl, tBu and OMe) appear to modulate the electrochemical properties and redox behaviour of the Zn(II), Ni(II) and Cu(II) diphenolate complexes. Cyclic voltammetric, spectroelectrochemical and EPR spectroscopic studies reveal the first oxidation processes of [Zn(tBuLOOMe)]and[Cu(tBuLOOMe)]are associated with ligand-based oxidation processes, yielding kinetically inert species possessing phenoxyl radical character. Conversely, the first oxidation process of [Ni(tBuLOOMe)] appears to be metal-based. Chapter 3 discusses of the syntheses of Schiff-base diphenolate and dithiolate complexes with a diamine bridge that incorporate pendant heterocyclic groups, with the potential to coordinate in an axial position to a metal centre that possess equatorial N2O2 or N2S2 coordination environments. We targeted the syntheses and characterisations of these complexes as analogues of the active site of NiSOD.Initial attempts to synthesise a diamine incorporating a pendant imidazole donor followed previously established synthetic approaches. The use of protecting groups to protect the NH group of the imidazole ring was unsuccessful. The syntheses of Ni(II) Schiff-base diphenolate and dithiolate complexes was attempted by using the pro-ligands, [H2tBuLOOH]and [H2tBuLSOH]and a post complexation step that involved a reaction of the OHpendant of the Schiff-base ligand with an aromatic or heterocyclic functionalised acid chloride. Functionalisations of the [Ni(tBuLOOH)]and [Ni(tBuLSOH)]to incorporatependant imidazole (Imid), pyridyl (PyN), furan (Fu) and pyrrole (Pyr) yielded crude products and attempts to purify these products proved unsuccessful.[Ni(tBuLOPh)]could be isolated and X-ray crystallographic studies of [Ni(tBuLOR)] (R = OH and Ph) and [Ni(tBuLSOH)] demonstrate that each centre adopts an approximate square planar geometry. Electrochemical investigations of [Ni(tBuLOR)] (R = OH, Ph)and[Ni(tBuLSOH)] showed that each exhibit irreversible redox processes and demonstrate that the OH and phenyl ester functionalities pendant to the ligand backbone do not stabilize theproducts formed following the oxidation of [Ni(tBuLOR)] (R = OH, Ph)and[Ni(tBuLSOH)]. Chapter 4 extends the research described in Chapter 3 through the synthesis of [Zn(tBuLOOH)] and [Cu(tBuLOOH)] and the attempted functionalisation of the OH group in these complexes to incorporate additionalpendant heterocyclic groups including imidazole(Imid), pyridyl (PyN), furan (Fu) and pyrrole (Pyr) together with phenyl (Ph). X-ray crystallographic studies show that [Cu(tBuLOOH)] possesses an approximately square planar coordination geometry with the metal centre bound by diimine and diphenolate donors. The frozen solution X-band EPR spectra of [Cu(tBuLOR)] (R =Ph, PyN, Fu, Pyr and Imid) are similar to one another and confirm each complex possesses a paramagnetic Cu(II) S = ½ d9 metal centre. The similarity between each EPR spectrum as R is varied suggests that the functional group pendant to the ligand backbonedoes not interact greatly with Cu (II) centre in [Cu(tBuLOR)]. [Zn(tBuLOOH)] was isolated and mass spectrometric data suggested that [Zn(tBuLOR)] (R =Ph, PyN, Fu, Pyr and Imid) had formed, however pure products could not be isolated. Electrochemical studies of [Cu(tBuLOR)] (R = OH, Ph, PyN, Fu, Pyr and Imid) revealtwo irreversible redox processes. [Cu(tBuLOPyN)] possesses first and second redox processes that are ca.0.14 V and 0.23V more positive than their [Cu(tBuLOR)] (R = OH, Ph, Fu, Pyr and Imid) counterparts. This suggests that the pyridyl functionalization of the pendant arm in [Cu(tBuLOPyN)]may stabilize its oxidation product. Chapter 5 provides a conclusion to the thesis and draws together the principal themes of each chapter.

Triazenides ligands, strategically substituted by aril groups [ N=N N(H) ] chains and containing NO2, CF3 e F groups in different positions were evaluated in relation to the occurrence of intermolecular interactions through secondary non-covalent bonding. The research is based on the single crystal X-ray diffraction to analysis of arrangements performed in the solid state. This work presents the synthesis and the investigation of the crystalline and molecular structure of twelve new molecules in the literature: the pró-ligands 1-(3-nitrophenyl)-3-(2-fluorophenyl)triazene,1-(3-trifluorometilphenyl)-3-(3nitrophenyl)triazeno and 1,3-bis(3-trifluorometilphenyl)triazene, and the mononuclear complexes de Cu(I), Cu(II), Ni(II) e Pd(II), trans-bis[1-(3-nitrophenyl)-3-(2-fluorophenyl)triazenide]bis(amin) Copper(II) (1), trans-{bis[1(3-nitrophenyl)-3-(2-fluorophenyl)triazenide]bis(pyridina)Copper(II)}.Pyridina (2), bis[1,3-bis(3-trifluorometilphenyl)triazenide]bis(pyridina)Copper(II) (3), trans-{bis[1-(3-trifluorometilphenyl)-3-(3-nitrophenyl)triazenide]bis(pyridina)Copper(II)} (4), trans-{bis[1-(2-fluorophenyl)-3-(3-trifluorometilphenyl)triazenide]bis(pyridina)Copper(II)} (5), {[1,3-bis(3-nitrophenyl)triazenido] bis-(triphenylfosfine) Copper(I)}.THF (6), trans-bis[1(3-nitrophenyl)-3-(2-fluorophenyl) triazenide]bis(pyridina)Nickel(II) (7), bis[1,3-bis(4-fluorometil- phenyl)triazenide]bis(pyridina)Nickel(II) (8) e trans-bis[1-(3-nitrophenyl)-3-(2-fluorophenyl) triazenide] bis(pyridina)Palladium(II) (9). Beside the structural analysis the compounds were characterized by melting point and infrared spectroscopy. Additionally, all pre-ligands were characterized by nuclear magnetic resonance and ultraviolet-visible spectroscopies. The complex (1) by electronic paramagnetic resonance. Specifically the complex (7) and (8) were analyzed for their UV-visible electronic spectra, molecular modeling and semi-empirical calculations for the correlation of spectra.

The structure of 3 consists of discrete Fe(II) units, each metal ion is six-coordinate in a distorted octahedral environment with four oxamate-oxygens from a H2pcpa- ligand in the basal plane and two water molecules in the apical position. 4 and 5 is a neutral zigzag chain of Mn(II) and Zn(II) ions, respectively, bridged by Hpcpa2- ligands exhibiting the bidentate/monodentate coordination mode. Each metal ion is building a somewhat distorted octahedral surrounding. The distance between metals ions intrachain is 11.456 Å (4) and 11.325 Å (5). Complex 6 consists of a dimer in which the Cu(II) ions is found in a square-shaped pyramidal geometry connected by two Hpcpa2- and the 2,2'-bipyridine as a terminal ligand.

O complexo 3 formou monocristais de cor laranja amarronzada, cuja a estrutura consiste em um monômero de Fe(II). Cada íon de Fe(II) é hexacoordenado com esfera de coordenação composta de duas moléculas de água posicionadas em trans e quatro oxigênios-oxamato de dois ligante H2pcpa-. Os compostos 4 e 5 formaram monocristais transparentes incolores cujas estruturas cristalinas são formadas por cadeias em ziguezague neutras de íons Mn(II) e Zn(II), respectivamente. Cada íon metálico está hexacoordenado com as três moléculas de água posicionadas em Meridional, dois oxigênios-oxamato de um ligante Hpcpa2- e um oxigênio-carboxilato de um outro grupo do Hpcpa2-. A distância entre os metais intracadeia Mn...Mn no complexo 4 é de 11,456 Å e Zn...Zn no complexo 5 é de 11,325 Å. O complexo 6 formou monocristais azuis, a estrutura consiste em um dímero em que o íon de Cu(II) encontra-se penta coordenado em uma geometria piramidal de base quadrada com dois íons de Cu(II) ligados por dois ligantes Hpcpa2- e com o ligante 2,2'-bipiridina atuando como ligante terminal.
