title: 2,3-Dihydro-1H-pyrrolo-[1,2-a]indole-9-carbonitrile.
abstract: The asymmetric unit of the title compound, C12H10N2, which may serve as a model for mitosenes, contains two independent mol-ecules. The conformation of the five-membered rings in both molecules is envelope, with the central CH2-CH2-CH2 C atom at the flap in each case. In the crystal, they inter-act by a combination of weak C-H⋯N and π-π inter-actions [centroid-centroid distances = 3.616 (1) and 3.499 (1) Å] and C-H⋯π contacts.
