Abstract: In the crystal structure of the title compound, [Cu₃Br₃(C₂₆H₂₄P₂)₃]·0.5CH₃COCH₃, two of the Cu centers are bridged by two bromide anions forming a Cu( [mu] -Br)₂Cu core, which is further bridged by a 1,2-bis(diphenylphosphino)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 molecule exhibits twofold disorder about an inversion centre at ( $1\over2$ , 1, 0). The crystal structure is stabilized by intermolecular C-HBr hydrogen bonds.
