Abstract

In the title complex, [Cu4Br(CN)3(C10H8N2)2]n, the four independent CuI atoms are all in distorted trigonal-planar geometries. One is formed by one N atom and one C atom from two cyanide groups and one Br atom, one is formed by two N atoms from two cyanide groups and one Br atom, and the other two are formed by two N atoms from a chelating 2,2′-bipyridine (bpy) ligand and one C atom from a cyanide group. The structure exhibits a zigzag chain backbone along [101] constructed by bromide and cyanide anions bridging the CuI atoms, with the [Cu(bpy)(CN)] units pointing laterally.
