9H-Carbazole-9-Carbo­thioic Di­thio­peroxy­anhydride

Abstract

The whole mol­ecule of the title compound, C26H16N2S4, is generated by twofold rotational symmetry. The carbazole skeleton is nearly planar [maximum deviation = 0.054 (5) Å]. In the crystal, aromatic π–π stacking is observed between parallel carbazole ring systems of adjacent mol­ecules, the shortest centroid–centroid distances between pyrrole and benzene rings being 3.948 (3) and 3.751 (3) Å.
