μ-1,2-Bis­(diphenyl­phos­phino)­ethane-κ(2) P:P′-bis­{[1,2-bis­(diphenyl­phosphino)­ethane-κ(2) P,P′]bromidocopper(I)} acetone disolvate

In the crystal structure of the title compound, [Cu(2)Br(2)(dppe)(3)]·2CH(3)COCH(3) [dppe is 1,2-bis­(diphenyl­phosphino)­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 mol­ecule is centrosymmetric, with the center of symmetry located between the methyl­ene C atoms of the bridging dppe ligand. The crystal structure is stabilized by intra­molecular C—H⋯Br hydrogen bonds and inter­molecular π–π inter­actions, with a centroid-to-centroid distance of 3.2055 (1) Å.
