Abstract:

The new Schiff base ligand L: (E)-N'-(pyridin-2-ylmethylene)acetohydrazide, was synthesized, and its reaction with Zn(II) ions form the complex: [ZnL2](ClO4)2, as confirmed by X-ray crystallography. This complex is stable in polar and non-polar solvents as proven by NMR. A significant enhancement in the fluorescence was observed from L upon coordination to Zn(II) ions over other transition metals such as Fe(II), Co(II), Ni(II), Cu(II), Cd(II) and Ag(I). These results suggest that L can be used as a selective flourosensor for the detection of Zn(II) ions.

Complexes of Co(II), Ni(II), Cu(II) and Zn(II) with 3-salicylidenehydrazono-2-indolinone were prepared. Their structure was established to be [MLCl].Cl by using elemental analysis and molar conductivity, as well as AA, FTIR, UV/VIS and 1H-NMR spectroscopic methods. The spectral studies indicated a square-planar geometry for the Ni(II) and Cu(II) complexes and a tetrahedral one for the Co(II) and Zn(II) complexes.

The coexistence of myo-inositol hexakisphosphate (IHP; phytate) and aqueous Zn(II) may affect the adsorbed amounts and speciation of each other on minerals, which can further influence the transport and fate of IHP and Zn(II) in soils and sediments. The objective of this study was to investigate the co-adsorption mechanism of IHP and Zn(II) on goethite (Gt). A combination of macroscopic experiments and in situ attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR) was used to investigate the co-adsorption of IHP and Zn(II) at the Gt–water interface in the pH range of 3

Abstract:

The field of bioinorganic chemistry has grown tremendously in the past 25 years. Much of the work is concerned with establishing the coordination site, ligand geometry and metal oxidation state in biologically active systems. The field also extends to the preparation and characterization of simpler model complexes that mimic the spectroscopic properties and perhaps some of the reactivity of the biological system. Much of this characterization work must precede meaningful mechanistic studies. Williams has provided an interesting overview of metal ions in biology from an inorganic perspective. There are several early review series and specialized journals devoted to the subject, and a recent issue of Chemical Reviews is devoted to the area. There also are several books covering general aspects of the subject. The field is so large and the systems are so individualistic that it is necessary, for the purposes of a text such as this, to choose a few sample systems as illustrative of the mechanistic achievements and problems. Studies of bioinorganic systems inevitably use some terminology from biochemistry which may be unfamiliar to an inorganic chemist. The examples in this Chapter are all metalloenzymes which catalyze some process. Clearly they contain a metal, but there are other components of an enzyme, and terms used to describe these are summarized as follows: An apoenzyme is a polypeptide whose composition, peptide sequence and structure depend on the biological source of the metalloenzyme. Typically, the molar mass of the polypeptide is in the range of 1.5-5xl05 daltons. The polypeptide is folded into coils and sheets whose shape is determined by electrostatics and hydrogen bonding. These terms designate the same type of component, but one or the other is used more commonly for a particular system. This is a nonprotein component which binds to the apoenzyme to produce the active catalyst. It is not covalently bonded to the apoenzyme and can be removed by relatively mild denaturation of the polypeptide. Common bioinorganic examples are coenzyme B12, discussed in Section 8.3, and Zn(II) in carbonic anhydrase, discussed in Section 8.4. A prosthetic group is analogous to a coenzyme except that a prosthetic group is believed to be covalently bonded to the apoenzyme.
