[1,2-Bis(diphenyl-phosphino)-1,2-dicarba-closo-dodeca-borane-κP,P'][7,8-bis-(di-phenyl-phosphino)-7,8-dicarba-nido-undeca-borato-κP,P']gold(I)-dichloro-methane-water (2/1/1).

The title compound, [Au(C(26)H(30)B(10)P(2))(C(26)H(30)B(9)P(2))]·0.5CH(2)Cl(2)·0.5H(2)O, contains two independent complex mol-ecules in the asymmetric unit. The gold(I) centres display a distorted tetra-hedral geometry. The complex is stablized through weak intra-molecular π-π stacking (Cg⋯Cg = 4.17†à ) and edge-to-face inter-actions (H⋯Cg = 3.21†à ). Adjacent mol-ecules inter-act through C-H⋯π (H⋯Cg = 2.88†à ) and B-H⋯π (H⋯Cg = 3.15†à ) contacts, forming a three-dimensional network, with solvent mol-ecules occupying the cavities. One of the phenyl groups was disordered over two sites with occupancy factors of 0.65 and 0.35.
