Crystal structure of 5-[2-(9H-carbazol-9-yl)ethyl]-1,3,4-oxadiazole-2(3H)-thione

Abstract

The title compound, C16H13N3OS, comprises an oxadiazolethione ring bound to the N atom of an almost planar carbazole ring system (r.m.s. deviation = 0.0088 Å) through an ethylene chain. The oxadiazole ring is inclined to the the carbazole ring system by 40.71 (6)°. In the crystal, N—H...O, N—H...S, C—H...N and C—H...S hydrogen bonds combine with C—H...π(ring) and π–π contacts to stack the molecules along the b-axis direction.
