tert-Butyl 2,3-dihydro-1H-cyclopenta[b]indole-4-carboxylate

In the title molecule, C16H19NO2, all the non-hydrogen atoms except two of the C atoms of thetert-butyl group lie on a crystallographic mirror plane. No classical hydrogen bonds are observed. The crystal packing is influenced by weak π–π and C—H...π interactions.
