Abstract
The title compound, [Cu2(CN)3(C10H8N2)]n, crystallizes as a cyanido‐bridged three‐dimensional polymeric structure, where there coexist CuI and CuII ions along with μ3‐ and μ2‐bridging cyanide groups. Each CuI ion is coordinated by four C atoms [Cu—C = 1.956 (3)–2.147 (3) Å] from two μ3‐ and two μ2‐cyanide groups in a tetrahedral environment. The CuII ion is coordinated by two N atoms from the 2,2′‐bipyridyl ligand and three N atoms from one μ3‐ and two μ2‐cyanide groups in a square‐pyramidal geometry [Cu—N = 1.967 (3)–2.183 (3) Å]. The CuI ions are paired by two C atoms from two cyanide groups into a dinuclear unit with a short CuI...CuI distance of 2.5398 (8) Å. Each dinuclear unit links six CuII ions by four μ2‐ and two μ3‐cyanide groups to form a 4,6‐connected framework, with CuI...CuII separations ranging from 4.864 (4) to 5.252 (4) Å.
