μ-1,2-Bis(diphenylphosphino)ethane-κ2P:P′-bis{[1,2-bis(diphenylphosphino)ethane-κ2P,P′]bromidocopper(I)} acetone disolvate

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—H...Br hydrogen bonds and intermolecular π–π interactions, with a centroid-to-centroid distance of 3.2055 (1) Å.
