The title compound, C26H21O3P, was obtained as by-product due to the hydrolysis of the desired tosylated compound. The dihedral angles between the three aromatic rings attached to the P atom lie in the range 78.1 (1)–87.6 (1)°. The hydroxymethyl group is disordered between two conformations in a 0.719 (9):0.281 (9) ratio. The hydroxy H atom is not involved in intermolecular interactions, while the hydroxy O atom serves as a donor for weak C—H...O hydrogen bonds, which link the molecules into chains propagating in [0-11].

Supramolecular Chains

In the title compound, C15H16N2S2, the central CN2S2residue is almost planar (r.m.s. deviation = 0.0354 Å) and forms dihedral angles of 56.02 (4) and 75.52 (4)° with the phenyl and tolyl rings, respectively; the dihedral angle between the aromatic rings is 81.72 (5)°. The conformation about the N—N bond isgauche[C—N—N—C = −117.48 (15)°]. Overall, the molecule has the shape of the letterL. In the crystal packing, supramolecular chains along theaaxis are formed by N—H...S(thione) hydrogen bonds whereby the thione S atom accepts two such bonds. The hydrogen bonding leads to alternating edge-shared eight-membered {...HNCS}2and 10-membered {...HNNH...S}2synthons. The chains are connected into layers by phenyl–tolyl C—H...π interactions; the layers stack along thecaxis with no specific interactions between them.
