Pyrrolo[2,1-c][1,4]benzodiazepine-5,11-dithione

The seven-membered fused-ring in the title compound, C12H12N2S2, adopts a boat conformation (with the two phenylene C atoms representing the stern and the methine C atom the prow). This methine C atom and the tertiary N atom also belong to a five-membered ring, which has an envelope conformation. In the crystal structure, molecules are linked about a center of inversion by pairs of N—H⋯S hydrogen bonds.
