In the mononuclear title complex, [Ag(SCN)(C18H15P)3], the AgIcenter is in a slightly distorted tetrahedral coordination geometry formed by one S atom from a terminal thiocyanate ligand and three P atoms from three triphenylphosphane ligands. In the crystal, weak C—H...N hydrogen bonds connect molecules into a two-dimensional network parallel to (10\overline{1}). One of the phenyl rings is disordered over two positions which were refined with an occupancy ratio of 0.715 (16):0.285 (16).
