Bruceolline D: 3,3-dimethyl-1H,4H-cyclopenta[b]indol-2(3H)-one
Acta Crystallographica Section E
The title compound, C13H13NO, crystallizes with four independent mol-ecules in the asymmetric unit. The 12-membered penta-[b]indole rings are essentially planar, with maximum deviations ranging from 0.034 (4) to 0.036 (4) Å in the four unique mol-ecules. In the crystal, weak C-H⋯O inter-actions are observed, which link the mol-ecules into chains along .
