title: 3,3-Dimethyl-1,2,3,4-tetra-hydro-cyclo-penta-[b]indole-1,2-dione (bruceolline E).
abstract: The title compound, C(13)H(11)NO(2), crystallizes with two mol-ecules in the asymmetric unit. The crystal packing is stabilized by N-H⋯O hydrogen bonds, which link the mol-ecules into chains along [10[Formula: see text]], and weak C-H⋯O inter-actions.
