In the title compound, [AuI(C(19)H(15)OP)(2)], the complete mol-ecule is generated by the application of twofold symmetry. The Au(I) atom is in a trigonal-planar geometry within an IP(2) donor set with the greatest distortion seen in the P-Au-P angle [128.49 (3) °]. Close intra-molecular Au⋯O inter-actions [3.172 (3) Å] are observed. No specific inter-molecular inter-actions are noted in the crystal packing.
