A series of pseudotetrahedral and octahedral zinc(n) complexes of the heteroscorpionate ligand bis(3, 5-dimethylpyrazolyl)(l-methyl-l-sulfanylethyl)methane (L3SH) have been synthesized and most characterized by X-ray crystallography. Pseudotetrahedral complexes isolated include [Zn(L3S)(CH3)]( [Zn(L3S)(Cl)], [Zn(L3S)(OAc)], [Zn(L3S)(SPhF5)], [Zn(L3S)(SBz>] (Bz = CH2Ph), [Zn(L3S)(OPh''-N00]) and [Zn(L3S)2]. In addition, the octahedral complex [Zn2{(L3S)2Zn} {O2P(OPh)2}, J was also synthesized. Comparisons between these complexes and those of the corresponding tris(pyrazolyl)borate, Tp~, or aromatic phenol or benzenethiolate ligands (L1O)~ and (L2S)~ reveal significant differences. Among these is a change in binding of acetate from pure unidentate to anisobidentate as the ligand donor is changed from S to N to 0. Trends such as these may aid in understanding how the donor set affects the structure and reactivity at pseudotetrahedral zinc centers in metalloproteins. The .Royal Society of Chemistry 2000.
