The title compound, [Au(C(8)H(7)ClNOS)(C(18)H(15)P)], is characterized by a linear S,P-donor set with a small deviation from the ideal linearity [S-Au-P = 175.14 (5)°] due to the close approach of the O atom to the Au atom [Au⋯O = 2.882 (3) Å]. Loosely associated dimers are formed in the crystal structure through C-H⋯O inter-actions.
