Reactions of M(OAc)2·nH2O and M(OAc)2(tmeda) with dithiocarboxylic acids gave [M(S2CTol)2]n (1) (M = Zn or Cd; Tol = C6H4Me-4) and [M(S2CAr)2(tmeda)] (3) (M = Zn, Cd, Hg; Ar = Ph or Tol), respectively, in high yields as deep-colored crystalline solids. The former are soluble in pyridine to give pyridine adducts [M(S2CTol)2(py)] (2). These complexes were characterized by elemental analysis, UV/Vis and
M(OAc)2·nH2O 和 M(OAc)2(tmeda) 与二硫代羧酸反应生成 [M(S2CTol)2]n (1)(M = Zn 或 Cd;Tol = C6H4Me-4)和 [M( S2CAr)2(tmeda)] (3)(M = Zn、Cd、Hg;Ar = Ph 或 Tol),分别以高产率作为深色结晶固体。前者可溶于吡啶,生成吡啶加合物 [M(S2CTol)2(py)] (2)。这些配合物通过元素分析、UV/Vis 和 NMR (1H, 13C) 光谱表征。电子光谱中的吸收被指定为配体到配体的电荷转移跃迁。单体物质 [Zn(S2CTol)2(py)] (2), [Zn(S2CPh)2(tmeda)] (3a), [Zn(S2CTol)2(tmeda)] (3b) 的晶体和分子结构和 [Cd(S2CTol)2(tmeda)] (3d) 已通过 X 射线晶体学确定。在[Zn(S2CTol)2
