研究了氰化铜-有机二亚胺体系中引入空间位阻取代基后的结构变化。氰化铜（I）和KCN与合适的螯合有机二亚胺配体的水热反应产生一系列一维氰化铜链，其被线性{（LL）Cu（CN）}（LL =有机二亚胺）侧链或被直接结合到母链的铜位点的二亚胺配体修饰。[Cu 3（CN）3（2，2 ′-bpy）]（1）（2，2 ′-bpy = 2，2 ′-bipyridine）和[Cu 3（CN）3（phen）]（2）（phen = 1，10-phen）的结构与文献报道的[Cu 4（CN）4（biquin）]（biquin = 2，2 ′-biquinoline）类似，均为一维{Cu（CN）}链，具有二亚胺-氰化铜侧臂.相反，[Cu 3（CN）3（biquin）2]（3）、[Cu 2（CN）2（dpbp）]、（4）（dpbp = 4，4 ′-二苯基-2，2 ′-联吡啶）和[Cu（CN）（dpphen）]（5）（dpphen = 4，7-二苯基-1，10-菲咯啉）的结构特征在于有机二亚胺配体直接连接到氰化铜链上。
The structural consequences of introducing sterically demanding substituents have been investigated for composite organic–inorganic materials of the copper cyanide–organodiimine system. The hydrothermal reactions of copper(I) cyanide and KCN, with the appropriate chelating organodiimine ligands yield a series of one-dimensional copper cyanide chains decorated either with linear {(LL)Cu(CN)} (LL = organodiimine) side chains or with diimine ligands bound directly to the copper sites of the parent chain. The structures of [Cu3(CN)3(2,2′-bpy)] (1) (2,2′-bpy = 2,2′-bipyridine) and [Cu3(CN)3(phen)] (2) (phen = 1,10-phenanthroline) are similar to that of the previously reported [Cu4(CN)4(biquin)] (biquin = 2,2′-biquinoline), exhibiting the characteristic one-dimensional {Cu(CN)} chain with diimine–copper cyanide side arms. In contrast, the structures of [Cu3(CN)3(biquin)2] (3), [Cu2(CN)2(dpbp)], (4) (dpbp = 4,4′-diphenyl-2,2′-bipyridine), and [Cu(CN)(dpphen)] (5) (dpphen = 4,7-diphenyl-1,10-phenanthroline) are characterized by direct attachment of the organodiimine ligand to the copper cyanide chain.
