[1,2-Bis(diphenylphosphino)-1,2-dicarba-closo-dodecaborane-κ2P,P′][7,8-bis(diphenylphosphino)-7,8-dicarba-nido-undecaborato-κ2P,P′]gold(I)–dichloromethane–water (2/1/1)

The title compound, [Au(C26H30B10P2)(C26H30B9P2)]·0.5CH2Cl2·0.5H2O, contains two independent complex molecules in the asymmetric unit. The gold(I) centres display a distorted tetrahedral geometry. The complex is stablized through weak intramolecular π–π stacking (Cg...Cg = 4.17 Å) and edge-to-face interactions (H...Cg = 3.21 Å). Adjacent molecules interact through C—H...π (H...Cg = 2.88 Å) and B—H...π (H...Cg = 3.15 Å) contacts, forming a three-dimensional network, with solvent molecules occupying the cavities. One of the phenyl groups was disordered over two sites with occupancy factors of 0.65 and 0.35.
