2-[(1-Methyl-1<i>H</i>-pyrrol-2-yl)methylidene]propanedinitrile

In the title compound, C(9)H(7)N(3), the N-bound methyl group and vinyl H atom are syn. The 12 non-H atoms comprising the mol-ecule are essentially coplanar (r.m.s. deviation = 0.071 Å). Supra-molecular tapes feature in the crystal packing, orientated perpendicular to [10-1], and are formed by C-H⋯N inter-actions involving each cyano N atom. The tapes are connected into layers via π-π inter-actions occurring between translationally related pyrrole rings [ring centroid-centroid distance = 3.8754 (10) Å]; the layers stack along the b axis.
