| Abstract: | Hydrothermal reaction of CuCN, K3[Fe(CN)6] and 1,10-phenanthroline affords a novel cyanide-bridged copper(I) coordination polymer [Cu3(CN)3(phen)]n (1). The complex displays an interesting one-dimensional neutral double helical framework with (phen)Cu–CN– side-arms as interchain bridges. The double helical chains are close packed in a parallel fashion, and the phen ligands stack in an interpenetrating mode, which leads to π–π interactions between parallel phen planes. The thermal stability and fluorescent property have also been investigated. |
