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

The title compound, [Cu(C(12)H(8)N(2))(C(27)H(26)P(2))]ClO(4), crystallizes with two Cu(I) complex cations and two perchlorate anions in the asymmetric unit. Each Cu(I) cation is four-coordinated by two P atoms of a 1,3-bis-(diphenyl-phosphan-yl)propane mol-ecule and two N atoms of a 1,10-phenanthroline ligand, with a coordination geometry that can be considered as distorted tetra-hedral. The crystal studied was twinned with a twin ratio of 0.786 (2):0.214 (2).

[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, [Cu(2)(CN)(2)(C(26)H(24)P(2))(3)]·2CH(3)OH, consists of two five-membered [Cu(dppe)CN] rings [dppe is 1,2-bis-(diphenyl-phosphino)ethane] bridged by one µ(2)-dppe ligand, and two methanol solvent mol-ecules. The angles around the central metal atom indicate that each Cu(I) atom is located in the center of a distorted tetra-hedron. The coordination sphere of each Cu(I) 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.
