Zinc thiolate complexes of three tridentate (N,N,S) ligands were prepared as models for the structure and function of thiolate alkylating zinc enzymes. N-(2-Mercaptoisobutyl)(2-pyridin-2-yl-methyl)amine (L1) forms isobutylthiolate-bridged dinuclear complexes with ZnN2S3 coordination. N-(2-Mercaptoisobutyl)(2-pyridin-2-yl-ethyl)amine (L2) yields isobutylthiolate-bridged dinuclear complexes in which

The title ligand MBPAH was obtained from 2-picolylamine and 2,2-dimethylthiirane. It forms the 2:1 zinccomplex (MBPA)2Zn, assumed to have a ZnN2S2 coordination with two uncoordinated nitrogen donor functions. Treatment of (MBPA)2Zn with alkylating agents or reaction of MBPAH with Zn(ClO4)2 yielded the complexes [(MBPA)4Zn3]X2 which were found by structure determinations to contain one ZnS4 and two
标题配体MBPAH获自2-吡啶甲基胺和2,2-二甲基噻喃。它形成2:1锌络合物(MBPA)2 Zn,假定它具有ZnN 2 S 2配位和两个未配位的氮供体功能。用烷基化剂处理(MBPA)2 Zn或MBPAH与Zn(ClO 4)2反应产生[(MBPA)4 Zn 3 ] X 2配合物,通过结构测定发现其含有一种ZnS 4和两种ZnN 4 S三核阳离子中2个单位。乙酸锌和MBPAH形成了硫醇盐桥连的双核络合物[(MBPA)Zn(OAc)]2,根据其结构确定其中包含两个ZNN 2小号2 O单元。
