6-Methyl-2,3,4,9-tetrahydro-1H-carbazole-1-thione

Abstract

In the title molecule, C13H13NS, the dihedral angle between the benzene ring and the fused pyrrole ring is 0.71 (8)° and the cyclohexene ring is in an envelope form. The (CH2)3 atoms of the cyclohexene ring are disordered over two positions; the site-occupancy factor for the major component refined to 0.862 (4). In the crystal, intermolecular N—H...S hydrogen bonds lead to the formation of centrosymmetric aggregates via an R22(10) ring.
