3-Benzhydryl-1,3,4-thiadiazole-2(3H)-thione
Abstract
In the title compound, C15H12N2S2, 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.
