Abstract
In the title compound, C9H7N3, the N-bound methyl group and vinyl H atom are syn. The 12 non-H atoms comprising the molecule are essentially coplanar (r.m.s. deviation = 0.071 angstrom). Supramolecular tapes feature in the crystal packing, orientated perpendicular to [101], and are formed by C-H center dot center dot center dot N interactions involving each cyano N atom. The tapes are connected into layers via pi-pi interactions occurring between translationally related pyrrole rings [ring centroid-centroid distance = 3.8754 (10) angstrom]; the layers stack along the b axis.
