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—HN 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.

In the title compound, C27H21N3O3, the cyclohexa-1,3-diene ring has a screw-boat conformation, and the fused ring system is folded, the dihedral angle between the outer benzene rings being 27.61 (6)°. The N-acetylacetamide residue (r.m.s. deviation = 0.0935 Å) has an anti conformation and is essentially perpendicular to the benzene ring to which it is connected [dihedral angle = 89.14 (6)°]; the methoxybenzene group is also twisted out of this ring [dihedral angle = 59.47 (7)°]. The three-dimensional architecture is consolidated by C—HO and C—Hπ interactions.
