determined by X-ray diffractometry. In all the H4DML complexes, the thiosemicarbazone acts as an N,N,Stridentate ligand, and the coordination polyhedra of the pentacoordinate metals are more or less distorted tetragonal pyramids. H4DMLO is an 0,N,S-tridentate ligand for zinc and cadmium halides and an N,S-bidentate ligand for mercury halides, in which the mercury atom has coordination number four and a distorted
第 12 族金属卤化物在乙醇中与 2-乙酰吡啶 4N-二甲基氨基硫脲 (H4DML) 和 2-乙酰基吡啶-N-氧化物 4N-二甲基氨基硫脲 (H4DMLO) 反应得到 [M(H4DML)X2] 形式的复合物 (1 - 9) [M(H4DMLO)X2] (10 - 18) (M = ZnII、CdII 或 HgII;X = Cl、Br 或 I)。H4DMLO 和两种缩氨基硫脲的配合物已通过元素分析和 IR 和 1H、13C 和 113Cd NMR 光谱以及 [Cd(H4 DML)Cl2 ] (4)、[Cd(H4 DML)l2 ] 的晶体结构进行表征(6)、H4DMLO、[Hg(H4DMLO)Cl2] (16) 和 [Hg(H4 DMLO)Br2] (17) 已通过 X 射线衍射测定。在所有 H4DML 配合物中,缩氨基硫脲作为 N,N,Stridentate 配体,五配位金属的配位多面体或多或少是扭曲的四方锥体。H4DMLO
