Abstract Reactions of group 10 transition metals with the ditopic ligand dipicolyldithiocarbamate (DPDTC) were performed. Thus, 1:2 reactions of [Ni(CH 3 COO) 2 ], [Pd(COD)Cl 2 ] or [Pt(COD)Cl 2 ] with DPDTC produced monomeric complexes of the type [M( κ 2 -SCS-DPDTC) 2 , M = Ni ( 1 ), Pd ( 2 ) or Pt ( 3 )] with the dithiocarbamate ligand (DTC) coordinated in a typical chelate κ 2 -SCS fashion. Interestingly, the reaction of [NiCl 2 ] with DPDTC, under similar conditions, afforded the organic compound 2-(pyridin-2-ylmethyl)imidazo[1,5-a]pyri-dine-3(2 H)-thione ( 4 ) as unique product. In order to prove the ditopic nature of the ligand DPDTC, complex [Pd( κ 2 -SCS-DPDTC) 2 ] ( 2 ) was further reacted with [ZnCl 2 ] in a 1:2 M ratio to yield the trinuclear complex [Cl 2 Zn( κ 2 -NN-DPDTC-SCS- κ 2 )Pd( κ 2 -SCS-DPDTC-NN- κ 2 )ZnCl 2 ] ( 5 ). The molecular structures of all compounds were determinate by typical analytical techniques including the unequivocal determination of all structures by single crystal X-ray diffraction analysis. As expected, complexes 1 – 3 are isostructural, and the metal centres exhibiting slightly distorted square-planar geometries. While in 5 , the trinuclear nature of the complex in confirmed exhibiting a nice combination of tetrahedral-square planar-tetrahedral geometries for the Zn-Pd-Zn centres respectively.

用于生产三核物种的双位二硫代氨基甲酸酯配体

摘要 进行了第 10 族过渡金属与双位配体二吡啶基二硫代氨基甲酸酯 (DPDTC) 的反应。因此，[Ni(CH 3 COO) 2 ]、[Pd(COD)Cl 2 ] 或 [Pt(COD)Cl 2 ] 与 DPDTC 的 1:2 反应产生 [M( κ 2 -SCS- DPDTC) 2 , M = Ni ( 1 ), Pd ( 2 ) 或 Pt ( 3 )] 与二硫代氨基甲酸酯配体 (DTC) 以典型的螯合物 κ 2 -SCS 方式配位。有趣的是，[NiCl 2 ] 与 DPDTC 在相似条件下的反应得到了有机化合物 2-(pyridin-2-ylmethyl)imidazo[1,5-a]pyri-dine-3(2 H)-thione ( 4 ) 作为独特的产品。为了证明配体 DPDTC 的双位性，配合物 [Pd(κ 2 -SCS-DPDTC) 2 ] ( 2 ) 与 [ZnCl 2 ] 以 1:2 M 的比例进一步反应，得到三核配合物 [Cl 2 Zn(κ 2 -NN-DPDTC-SCS-κ 2 )Pd(κ 2 -SCS-DPDTC-NN-κ 2 )ZnCl 2 ] ( 5 )。所有化合物的分子结构均通过典型的分析技术确定，包括通过单晶 X 射线衍射分析明确确定所有结构。正如预期的那样，配合物 1-3 是同构的，金属中心呈现出轻微扭曲的方形平面几何形状。而在 5 中，复合物的三核性质证实了锌-钯-锌中心分别表现出四面体-正方形平面-四面体几何形状的良好组合。
