4a-Methyl-2,3,4,4a-tetra-hydro-1H-carbazole-6-sulfonamide

Abstract

In the title mol-ecule, C13H16N2O 2S, the nine non-H atoms comprising the indole residue are approximately coplanar (r.m.s. deviation = 0.031 Å). The partially saturated ring adopts a chair conformation. One amine H forms an inter-molecular N-H⋯O hydrogen bond to a sulfonamide O atom, while the other amine H form is connected to the indole N atom of an adjacent mol-ecule via an N-H⋯N hydrogen bond, resulting in a three-dimensional architecture.
