[μ-1,2-Bis(diphenyl-phosphino)ethane-κP:P']bis-{[1,2-bis-(diphenyl-phosphino)ethane-κP,P']cyanidocopper(I)} methanol disolvate.

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.

[1,3-Bis(diphenyl-phosphan-yl)propane-κP,P'](1,10-phenanthroline-κN,N')copper(I) perchlorate.

The title compound, [Cu(C12H8N2)(C27H26P2)]ClO4, crystallizes with two CuI complex cations and two perchlorate anions in the asymmetric unit. Each CuI cation is four-coordinated by two P atoms of a 1,3-bis(diphenylphosphanyl)propane molecule and two N atoms of a 1,10-phenanthroline ligand, with a coordination geometry that can be considered as distorted tetrahedral. The crystal studied was twinned with a twin ratio of 0.786 (2):0.214 (2).
