3-Benzhydryl-1,3,4-thia­diazole-2(3H)-thione

In the title compound, C(15)H(12)N(2)S(2), the two phenyl rings and the planar (r.m.s. deviation = 0.002 Å) thia­diazole ring adopt a propeller conformation about the central C—H axis with H—C—C—C(phen­yl) torsion angles of 44 and 42° and an H—C—N—C(thia­diazole) torsion angle of 28°. Intra­molecular C—H⋯S and C—H⋯N contacts are observed. In the crystal, centrosymmetrically related mol­ecules associate through C—H⋯π inter­actions. These are connected into a supra­molecular chain along [101] by C—H⋯N inter­actions.
