The asymmetric unit of the title compound, [AuCl(C31H32NP)]·0.25CHCl3, contains two independent complex molecules and half a chloroform solvent molecule, which is disordered across an inversion center. The AuI ions are each coordinated in a slightly distorted linear environment, with P-Au-Cl angles of 177.20 (4) and 178.54 (4)°.
