Abstract

The suitability of bis(pyrazolyethyl) ether ligands of zinc and cobalt in providing an NNO donor system that may model the binding of zinc to the protein backbone in enzymes such as thermolysin is discussed. Results indicate that the ether ligands are not particularly suitable in modeling the bioinorganic aspects of zinc chemistry, with cobalt more suited to this purpose.

2. Structural studies of the [tris(imidazolyl)phosphine]metal nitrate complexes {[pim(super Pr(super i),Bu(super t))]M(NO3)}(super +) (M = Co, Cu, Zn, Cd, Hg): comparison of nitrate-binding modes in synthetic analogues of carbonic anhydrase

Abstract

X-ray diffraction studies on a series of cationic divalent metal domplexes supported by the tris(1-isopropyl-4-tert-butylimidazolyl)phosphine ligand, {[pim(super Pr(super i),Bu(super t))]M(NO3)}(super +) (M = Co, Cu, Zn, Cd, Hg), demonstrate that the nitrate ligand coordination mode is strongly dependent upon the metal. In view of the steric demands of two ligand systems, the fine-tuning that is necessary to create synthetic analogues that accurately mimic the chemistry of metalloenzymes is accentuated.
