Crystal structure of a new modification of the cyanide-bridged copper(I) coordination compound [CuCN(bpy)] n

Abstract

The hydrothermal reaction of CuCN and bpy in the presence of an octahedral cluster complex K2.75Cs1.25[Re6Se8(CN)4(OH)2]·H2O affords a cyanide-bridged chain coordination polymer [CuCN(bpy)]n (bpy — 2,2′-bipyridyl) (1). The structure is monoclinic, space group C2/c, a = 22.848(2) A, b = 7.7182(8) A, c = 14.4331(13) A, β = 127.805(2)°, V = 2010.9(3) A3, Z = 8, dx = 1.623 g/cm3. Copper atoms have a tetrahedral coordination environment formed by N atoms of the bpy molecule as well as N and C atoms of ambidentate bridging CN ligands.
