Reactions of tetraphenylphosphonium dibromoaurate(I) with 1,2-bis(diphenylphosphino)-1,2-dicarba-closo-dodecaborane in 2:1 ratio in acetone solution yields brown crystals shown to be the title compound. A single crystal X-ray study shows coordination of AuBr moieties by the phosphorus atoms of the ligand (Au-P 2.253(1), 2.246(1); Ag-Br 2.4041(7), 2.4067(7) Å), permitting a close Au⋯Au contact (2.9536(3)Å) with concomitant bending of the P-Au-Br arrays (173.99(4), 166.14(4)°) and a Br-Au⋯Au-Br torsion of 47.80(2)°.
