μ-1,2-Bis(diphenylphosphino)ethane-κ2P:P′]bis{[1,2-bis(diphenylphosphino)ethane-κ2P,P′]cyanidocopper(I)} methanol disolvate

Abstract

The title centrosymmetric complex, [Cu2(CN)2(C26H24P2)3]·2CH3OH, consists of two five-membered [Cu(dppe)CN] rings [dppe is 1,2-bis­(diphenyl­phosphino)ethane] bridged by one μ2-dppe ligand, and two methanol solvent mol­ecules. The angles around the central metal atom indicate that each CuI atom is located in the center of a distorted tetra­hedron. The coordination sphere of each CuI atom is formed by three P atoms from two dppe ligands, and one C atom from the cyanide ligand. The crystal structure is stabilized by O—H⋯N hydrogen bonds, which are formed by the O—H donor group from methanol and the N-atom acceptor from a cyanide ligand.
