3,3-Dimethyl-1,2,3,4-tetrahydrocyclopenta[b]indole-1,2-dione (bruceolline E)

Abstract

The title compound, C13H11NO2, crystallizes with two molecules in the asymmetric unit. The crystal packing is stabilized by N—H...O hydrogen bonds, which link the molecules into chains along [10-1], and weak C—H...O interactions.
