Abstract

In the title compound, Cd(C(7)H(7)S)(2)(C(13)H(14)N(2)), the unique Cd(II) ion, located on a twofold rotation axis, is coordinated by two S atoms and two N atoms in a slightly distorted tetra-hedral environment. Symmetry-related Cd(II) ions are linked via bridging 1,3-di-4-pyridylpropane ligands, forming a zig-zag chain-structure parallel to [001]. In the crystal structure, there are weak intra-chain π-π stacking inter-actions between benzene rings, with a centroid-centroid distance of 3.825 (7) Å, and pairs of chains are inter-digitated with respect to the 4-methyl-benzene-thiol-ate groups.

摘要

在标题化合物[Cd(C₇H₇S)₂(C₁₃H₁₄N₂)]ₙ中,位于二重旋转轴上的独特Cd(II)离子在略微扭曲的四面体环境中由两个S原子和两个N原子配位。对称相关的Cd(II)离子通过桥连的1,3 - 二(4 - 吡啶基)丙烷配体相连,形成平行于[001]的之字形链结构。在晶体结构中,苯环之间存在链内弱π - π堆积相互作用,质心 - 质心距离为3.825 (7) Å,并且链对相对于4 - 甲基苯硫醇盐基团相互交错。
