Tris[μ-1,2-bis(diphenylphosphino)ethane]-1:2κ2P:P′;1:3κ2P:P′;2:3κ2P:P′-di-μ-bromido-1:2κ4Br:Br-bromido-3κBr-tricopper(I) acetone hemisolvate

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(μ-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 (1over2, 1, 0). The crystal structure is stabilized by intermolecular C—H...Br hydrogen bonds.
