title: μ-1,2-Bis-(diphenyl-phos-phino)-ethane-κP:P'-bis-{[1,2-bis-(diphenyl-phosphino)-ethane-κP,P']bromidocopper(I)} acetone disolvate.
abstract: In the crystal structure of the title compound, [Cu(2)Br(2)(dppe)(3)]·2CH(3)COCH(3) [dppe is 1,2-bis-(diphenyl-phosphino)-ethane, C(26)H(24)P(2)], the two Cu centers are bridged by a dppe ligand and each metal center carries one chelating dppe unit, with the fourth coordination site available for the Br(-) anion. The mol-ecule is centrosymmetric, with the center of symmetry located between the methyl-ene C atoms of the bridging dppe ligand. The crystal structure is stabilized by intra-molecular C-H⋯Br hydrogen bonds and inter-molecular π-π inter-actions, with a centroid-to-centroid distance of 3.2055 (1) Å.
