Tris[μ-1,2-bis-(diphenyl-phosphino)-ethane]-1:2κP:P';1:3κP:P';2:3κP:P'-di-μ-bromido-1:2κBr:Br-bromido-3κBr-tricopper(I) acetone hemisolvate.

In the crystal structure of the title compound, [Cu(3)Br(3)(C(26)H(24)P(2))(3)]·0.5CH(3)COCH(3), two of the Cu centers are bridged by two bromide anions forming a Cu(μ-Br)(2)Cu core, which is further bridged by a 1,2-bis-(diphenyl-phosphino)-ethane (dppe) ligand. The third Cu center is terminally bound to another bromide ligand and is connected to the other two Cu atoms by bridging dppe ligands, forming a triangular cluster unit. The acetone solvent mol-ecule exhibits twofold disorder about an inversion centre at (, 1, 0). The crystal structure is stabilized by inter-molecular C-H⋯Br hydrogen bonds.
