(E)-N-(1H-Pyrrol-2-ylmethylidene)-2-{[(E)-(1H-pyrrol-2-ylmethylidene)amino]methyl}aniline

Abstract

The title salophene-type compound, C 17 H 16 N 4 , 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-HÁ Á ÁN hydrogen bonds, forming chains propagating along the a-axis direction. The chains are linked by C-HÁ Á Á interactions, forming a three-dimensional supramolecular structure.
