Abstract: In the crystal structure of the title compound, [Cu₂Br₂(dppe)₃]·2CH₃COCH₃ [dppe is 1,2-bis(diphenylphosphino)ethane, C₂₆H₂₄P₂], 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-HBr hydrogen bonds and intermolecular - interactions, with a centroid-to-centroid distance of 3.2055 (1) Å.
