In the title compound, [Au(C(5)H(10)NOS)(C(18)H(15)P)], the Au(I) atom is linearly coordinated within an S,P-donor set with distortion from an ideal linear geometry [S-Au-P = 176.71 (6)°] due to an intra-molecular Au⋯O contact [2.943 (4) Å]. In the crystal structure, centrosymmetrically related mol-ecules associate via C-H⋯O inter-actions.
