Abstract

In the title compound, (C(5)H(7)N(2))(2)[CoCl(4)], the cobalt(II) ion is coordinated by four chloride ions in a slightly distorted tetra-hedral geometry. The crystal packing is stabilized by inter-molecular N-H⋯Cl hydrogen bonding, forming a three-dimensional network. The crystal was a non-merohedral twin emulating tetra-gonal symmetry, but being in fact ortho-rhom-bic.

摘要

在标题化合物（C₅H₇N₂）₂[CoCl₄]中，钴（II）离子由四个氯离子以略微扭曲的四面体几何构型配位。晶体堆积通过分子间N-H⋯Cl氢键得以稳定，形成三维网络。该晶体为非镜像孪晶，模拟四方对称，但实际上为正交晶系。
