(R)-(+)-[μ-2,2′-Bis(diphenylphosphino)-1,1′-binaphthalene-κ²P:P′]bis[chloridogold(I)] dichloromethane solvate

In the crystal structure of the title compound, [Au₂Cl₂(C₄₄H₃₂P₂)]·CH₂Cl₂, the molecule is located on a twofold axis. The naphthyl group is slightly bent; the angle between the planes of the two six-membered rings is 3.5 (5)°. The angle between the mean planes of the two symmetry-related naphthyl groups is 84.4 (1)°. The P—Au—Cl group is almost linear, with an angle of 175.5 (1)°. The dichloromethane solvent molecule lies on a twofold axis and connects the AuCl groups of two symmetry-related molecules via intermolecular C—H...Cl hydrogen bonding.
