In the title compound, [Cu(CHNO)(CHN)], the Cu cation is situated on an inversion center and is coordinated by the N atoms of two di-methyl-amine ligands and the carboxyl-ate O atoms of two 4-(1,2,4-triazol-1-yl)benzoate anions, leading to a slightly distorted square-planar NO coordination environment. In the crystal, inter-molecular N-H⋯N hydrogen bonds between the amine function and the central N atom of the triazole ring lead to the formation of ribbons parallel to [11]. Weak inter-molecular C-H⋯O hydrogen-bonding inter-actions are also observed that consolidate the crystal packing.
在标题化合物[Cu(CHNO)(CHN)]中，铜阳离子位于一个对称中心上，由两个二甲胺配体的N原子和两个4-(1,2,4-三唑-1-基)苯甲酸根阴离子的羧酸根O原子配位，形成一个稍有扭曲的平面正方形NO配位环境。在晶体中，胺官能团与三唑环中心N原子之间的分子间N-H⋯N氢键导致形成平行于[11]的带状结构。还观察到弱的分子间C-H⋯O氢键相互作用，这巩固了晶体堆积。
