In the crystal, mol-ecules are linked into two-dimensional networks parallel to (100) via inter-molecular N - H?N and weak C - H?N hydrogen bonds. The crystal packing is further consolidated by weak ?-? stacking inter-actions, with a centroid-centroid distance of 3.590 (2) . The crystal studied was an inversion twin with a 0.37 (13):0.63 (13) domain ratio.Article
