In the title compound, [Zn(2)(C(22)H(36)NS(2))(4)], two bidentate dithio-carbamate groups chelate directly to the Zn(II) atoms, whereas the two remaining dithio-carbamate ligands bridge the Zn atoms via a crystallographic inversion centre. The Zn atoms show a strongly distorted tetra-hedral geometry. Adding the long S⋯S distance with the inversion centre being in the middle, the resulting five-coordinate geometry around the Zn atoms can be considered to be between distorted recta-ngular pyramidal and trigonal bipyramidal, with a calculated τ value of 0.31. In this dimer complex, two inversion-related tetra-decyl carbon chains exhibit all-trans conformations, and the other two chains show a cis conformation at the end of the chains.
在标题化合物[Zn₂(C₂₂H₃₆NS₂)₄]中，两个二齿二硫代氨基甲酸盐基团直接螯合到Zn(II)原子上，而其余两个二硫代氨基甲酸盐配体通过一个晶体学反演中心桥连Zn原子。Zn原子呈现出严重扭曲的四面体几何构型。加上反演中心位于中间的长S⋯S距离，Zn原子周围形成的五配位几何构型可被认为介于扭曲的矩形金字塔和三角双锥之间，计算得到的τ值为0.31。在这个二聚体配合物中，两条与反演相关的十四烷基碳链呈现全反式构象，另外两条链在链端呈现顺式构象。
