Hydrothermal synthesis and crystal structure of a novel cyanide-bridged double helical copper(I) coordination polymer [Cu_3(CN)_3(phen)]_n

摘要

Hydrothermal reaction of CuCN,K_3[Fe(CN)_6] and 1,10-phenanthroline affords a novel cyanide-bridged copper(I) coordination polymer [Cu_3(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 n-n interactions between parallel phen planes.The thermal stability and fluorescent property have also been investigated.
