MetadataShow full item record
The title compound, [((2-MeC6H4)Ph2P)( MeCN )CuBr2Cu( MeCN )(PPh2-MeCH)]2MeCN has been isolated in the course of recrystallization of a 1 : 1 stoichiometric ratio of copper(]) bromide and the phosphine ligand from acetonitrile and characterized by a single-crystal X-ray structure determination. Crystals are triclinic, PI, a 13.148(2), b 10.673(2), c 8.101(1) Š, a 84.24(4), ߠ89.42(4), ? 82.02(2)ଠZ= 1 dimer ; R was 0.050 for 1772 independent 'observed' reflections. The dimer is centrosymmetric and is the first 1 : 1 : 1 mixed base copper(1) halide : phosphine : nitrile adduct to be so isolated and so characterized.
