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 Å). Supramolecular tapes feature in the crystal packing, orientated perpendicular to [10-1], and are formed by C—H⋯N interactions involving each cyano N atom. The tapes are connected into layers via π–π interactions occurring between translationally related pyrrole rings [ring centroid–centroid distance = 3.8754 (10) Å]; the layers stack along the b axis.
