1-[Chloro(diphenylphosphino)gold(I)-P]-2-phenyl-1,2-dicarba-closo-dodecaborane(12)

The title compound, 1-[(C₆H₅)₂PAuCl]-2-(C₆H₅)-1,2-closo-C₂B₁₀H₁₀ or [AuCl{(C₆H₅)₂P(C₈H₁₅B₁₀)}] is the first reported derivative of 1-[(C₆H₅)₂P]-2-(C₆H₅)-1,2-closo-C₂B₁₀H₁₀. The conformation of the cage phenyl group is comparable with the parent carbaborylphosphine, however the (C₆H₅)₂PAuCl substituent is less tilted from an idealized radial position on C1 due to a balance between two opposing sets of intramolecular forces. The P-Au-Cl fragment adopts the expected linear geometry.
