Crystal Packing in Equilibrating Systems: A Single Crystal Containing Three Isomers of CuCl(1-pyridin-2-yl-3-<i>p</i>-tolyl-thiourea)₂

The X-ray crystal structure of the labile copper(I) complex CuCl(1-pyridin-2-yl-3-p-tolyl-thiourea)2 comprises three different isomers and has profound implications for work on the understanding and prediction of low-symmetry crystal packing. A chloroform co-crystal of one of these isomers is also reported along with a related compound of (6-methyl-benzothiazol-2-yl)-pyridin-2-yl-amine.活性铜(I)配合物CuCl(1-吡啶-2-基-3-对甲苯基硫脲)₂的X射线晶体结构包含三种不同的异构体，该研究结果对理解与预测低对称性晶体堆积的相关工作具有重要指导意义。本研究同时报道了其中一种异构体的氯仿共晶体，以及一种相关的(6-甲基苯并噻唑-2-基)-吡啶-2-胺类化合物。
