Abstract
The title salophene-type compound, C17H16N4, crystallizes with two independent molecules (A and B) in the asymmetric unit. Both (pyrrol-2-yl)methanimine groups have an extended conformation, and an E conformation about the C=N bonds. The pyrrole rings are inclined to the aminobenzylamine ring by 43.7 (3) and 78.9 (2)° in molecule A, and by 46.8 (3) and 79.3 (3)° in molecule B, while the pyrrole rings are inclined to one another by 58.9 (3) and 59.9 (3)° in molecules A and B, respectively. In the crystal, molecules are linked by N—H...N hydrogen bonds, forming chains propagating along the a-axis direction. The chains are linked by C—H...π interactions, forming a three-dimensional supramolecular structure.
