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 molecules. 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 interact by a combination of weak C—H...N and π–π interactions [centroid–centroid distances = 3.616 (1) and 3.499 (1) Å] and C—H...π contacts.
