3,9-Dimethyl-2,3-Dihydro­Spiro­[Carb­Az­Ole-1,2′-[1,3]Dithio­Lan]-4(9H)-One

Abstract

The title compound, C16H17NOS2, consists of a carbazole skeleton with methyl and dithiol­ane groups as substituents. In the indole ring system, the benzene and pyrrole rings are nearly coplanar, forming a dihedral angle of 1.02 (11)°. The cyclo­hexenone ring has a twisted conformation, while the dithiol­ane ring adopts an envelope conformation with one of the CH2 C atoms at the flap. In the crystal, weak C—H⋯O hydrogen bonds link the mol­ecules into supra­molecular chains nearly parallel to the c axis. These hydrogen bonds together with weak C—H⋯π inter­actions link the molecules into a three-dimensional supramolecular network.
