摘要: A series of pseudotetrahedral and octahedral zinc(II) complexes the heteroscorpionate ligand bis(3,5-dimethylpyrazolyl)(1-methyl-1-sulfanylethyl)methane (L3SH) have been synthesized most characterized by X-ray crystallography. Pseudotetrahedral isolated include [Zn(L3S)(CH3)], [Zn(L3S)(Cl)], [Zn(L3S)(OAc)], [Zn(L3S)(SPhF5)], [Zn(L3S)(SBz)] (Bz = CH2Ph), [Zn(L3S)(OPhp-NO2)], [Zn(L3S)2]. In addition, complex [Zn2{(L3S)2Zn}{O2P(OPh)2}4] was also synthesized. Comparisons between these those corresponding tris(pyrazolyl)borate, Tp−, or aromatic phenol benzenethiolate ligands (L1O)− (L2S)− reveal significant differences. Among is a change in binding acetate from pure unidentate to anisobidentate as donor changed S N O. Trends such may aid understanding how set affects structure reactivity at zinc centers metalloproteins.
