The title compound, [Sn(CH)(CHNOS)], has the Sn atom bound by two methyl groups which lie over the weaker Sn-S bonds formed by two asymmetrically chelating di-thio-carbamate ligands so that the coordination geometry is skew-trapezoidal bipyramidal. The most prominent feature of the mol-ecular packing are secondary Sn⋯S inter-actions [Sn⋯S = 3.5654 (7) Å] that lead to centrosymmetric dimers. These are connected into a three-dimensional architecture methyl-ene-C-H⋯S and methyl-C-H⋯O(morpholino) inter-actions. The Sn⋯S inter-actions are clearly evident in the Hirshfeld surface analysis of the title compound along with a number of other inter-molecular contacts.
标题化合物[Sn(CH)(CHNOS)]中，锡原子与两个甲基相连，这两个甲基位于由两个不对称螯合二硫代氨基甲酸盐配体形成的较弱的Sn-S键上方，因此配位几何形状为斜梯形双锥。分子堆积的最显著特征是导致中心对称二聚体的次级Sn⋯S相互作用[Sn⋯S = 3.5654 (7) Å]。这些通过亚甲基-C-H⋯S和甲基-C-H⋯O(吗啉代)相互作用连接成三维结构。在标题化合物的 Hirshfeld 表面分析中，Sn⋯S相互作用以及许多其他分子间接触都清晰可见。
