摘要

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.
