The title complex, [Cu-2(C10H4N4)(C41H39P3)(2)](BF4)(2).CH2Cl2, was synthesized and characterized. Two copper(I) ions are bridged by 4,4';-di-4-pyridyldiazene (more commonly as 4,4';-azobipyridine). The discrete dinuclear cation contains two distorted tetrahedral copper(I) centers. Each Cu-I atom is coordinated by one 1,1,1-tris(diphenylphosphinomethyl)ethane molecule and one 4,4';-azobipyridine ligand. The complex sits on a center of symmetry; the solvent molecule is disordered across another center of symmetry. On irradiation of the copper(I) complex in dichloromethane at 365 nm, the trans/cis ratio of the complex is reversed.
