Abstract:

The current study aimed to synthesise, characterise, and investigate the antimicrobial activity of homonuclear Cu(II) and Ni(II) Schiff base complexes. Homonuclear Schiff Base Complexes chelates of Cu(II) and Ni(II) were synthesised. It appears that the complex is a potential metallo-ligand. It forms binuclear complexes when it reacts with two different metal salts, Ni and Cu. Using a Schiff base ligand made from 4-chloro-o-phenylenediamine and 3,5-dichloro-2-hydroxyacetophenone, the homo and hetero binuclear oxygen bridging Cu(II) and Ni(II) complexes were synthesized.

In order to study the effects of R group on Fe-Hg interactions and 31P NMR, the structures of mononuclear complexes [Fe(CO)3(RPhPpy)2] (1: R = Me; 2: R = Et; 3: R = Ph) and binuclear complexes [Fe(CO)3(RPhPpy)2(HgCl2)] (4: R = Me; 6: R = Et; 6: R = Ph) were calculated by density functional theory (DFT) PBE0 method. Moreover, the 31P NMR chemical shifts were calculated by PBE0-GIAO method. The replacement of Ph group in Ph2Ppy ligands with Me or Et group results in higher stabilities and stronger Fe-Hg interactions. The stabilities of binuclear complexes follow the order of 5 > 4 >6.

The relationships between geometric parameters of the complexes' molecules, the structural features of their coordination polyhedra and the probability of mesophase behavior were considered. According to the calculated parameters of Voronoi-Dirichlet polyhedra, the structural features of the first coordination sphere o

A series of novel binuclear transition metal complexes was synthesized by reaction of a Schiff base ligand (1-Methyl-2-(2-oxo-1,2-dihydro-pyrimidin-4-ylimino)-propylideneamino-acetic acid) (LaH) derived from 4-amino-pyrimidine-2-one, diacetyl, glycine and corresponding chloride salt of Cu(II), Ni(II), Co(II) and Zn(II) metals in 1:1 (metal : ligand) molar ratio. The compounds were characterized by elemental analyses, molar conductance measurement, magnetic moment measurement and various spectral studies viz. IR, UV-visible, 1H-NMR, 13C-NMR, EPR and ESI-MS.

Abstract:

Oligonuclear complexes as well as coordination polymers with various network topologies can be obtained by using homo- or heterobinuclear complexes as starting materials. These building blocks are stable complexes, where the metal ions are held together by compartmental ligands, or alkoxo-bridged Cu(II) species. The binuclear nodes can be connected through appropriate exo-dentate ligands, or through metal-containing anions (e.g., [M(CN)6]3-, M = CrIII, FeIII, CoIII). A rich variety of 3d-3d and 3d-4f heterometallic complexes, with interesting architectures and topologies of the spin carriers,

Abstract:

The title compound, [Cu2(C14H18N2OS2)2], is a binuclear copper(II) complex of an oxybenzylidenedithiocarbazate ligand. The ligand coordinates in a tridentate manner through N-, S- and O-donor atoms. Each O atom also bridges to a second CuIIion to form the binuclear species. It has a central Cu2O2rhomboid moiety and a metal-to-metal separation of 2.9923 (6) Å. In the crystal, the binuclear complexes stack along theaaxis with all the hexyl chains located side-by-side, forming a hydrophobic region. The complexes are linkedviaC—H...N hydrogen bonds, forming chains along thec-axis direction. One Cu

Abstract:

Binuclear diaminocarbene complexes, which form as a regioisomer mixture in the reaction between isocyanide–palladium(II) complex cis-[PdCl2(CNXyl)2] and 1,3-thiazol-2-amine, are able to exchange an anionic chloride ligand with other halides, such as Br or I. This process also affords binuclear complexes as mixtures of kinetically and thermodynamically controlled regioisomers. In CDCl3 solutions, we observed interconversion of kinetically and thermodynamically controlled regioisomers. The results of the DFT calculations revealed that in CHCl3 solution, each pair of the isomers exhibited two dif
