From the reaction of copper(II) chloride dihydrate with , -dimethyl- -(pyridin-2-ylmeth-yl)ethane-1,2-di-amine (denoted N^N^N) a new species comprising three distinct complexes crystallized, namely, aqua-chlorido-[ , -dimethyl- -(pyridin-2-ylmeth-yl)ethane-1,2-di-amine-κ ,','']copper(II)chlorido-[ , -dimethyl- -(pyridin-2-ylmeth-yl)ethane-1,2-di-amine-κ ,','']copper(II) tetra-chlorido-cuprate(II), [CuCl(CHN)(HO)][CuCl(CHN)][CuCl] or [Cu(N^N^N)(HO)Cl][Cu(N^N^N)Cl][CuCl], the latter two of which form an adduct. This complex was reacted with ammonium thio-cyanate to form [Cu(N^N^N)(NCS)], which crystallized with two independent mol-ecules and a partial water in the asymmetric unit very similarly to the already reported structure of this compound. Both crystal structures show a rather complex set of inter-molecular inter-actions including hydrogen bonding and what may be described as chalcogen bonding, pnictogen bonding and/or coinage bonding. The mol-ecular structures, intra-molecular inter-actions and packing patterns are discussed in detail and the more unusual ones are set into the context of structures available in the literature.
通过二水合氯化铜与N,N-二甲基-N-(吡啶-2-基甲基)乙烷-1,2-二胺（记为N^N^N）反应，结晶出一种包含三种不同配合物的新物质，即水合氯ido-[N,N-二甲基-N-(吡啶-2-基甲基)乙烷-1,2-二胺-κN,N',N'']铜(II)氯ido-[N,N-二甲基-N-(吡啶-2-基甲基)乙烷-1,2-二胺-κN,N',N'']铜(II)四氯ido铜酸盐(II)，[CuCl(CHN)(H₂O)][CuCl(CHN)][CuCl₄]或[Cu(N^N^N)(H₂O)Cl][Cu(N^N^N)Cl][CuCl₄]，其中后两者形成加合物。该配合物与硫氰酸铵反应形成[Cu(N^N^N)(NCS)]₂，其在不对称单元中结晶出两个独立分子和一个部分水分子，与该化合物已报道的结构非常相似。两种晶体结构均显示出一组相当复杂的分子间相互作用，包括氢键以及可被描述为硫属元素键、氮族元素键和/或金属键的相互作用。详细讨论了分子结构、分子内相互作用和堆积模式，并将更不寻常的情况置于文献中现有结构的背景下。
