| Abstract: | 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)°. |
