[2,2'-Bis(di-phenyl-phosphan-yl)-1,1'-binaphthyl-κ2 P,P']di-chlorido-platinum(II) acetonitrile trisolvate.

The crystal structure (150 K) of the racemic title compound, [PtCl2(C44H32P2)]·3CH3CN, has been determined. The asymmetric unit comprises a single mol-ecule of the title compound co-crystallized with three aceto-nitrile solvent mol-ecules. Four mol-ecules are observed in the unit cell, with R and S enanti-omers present in a 2:2 ratio. Evidence of intra-molecular π-stacking is observed with no discernable inter-molecular inter-actions.
