Abstract:
The title compound, C16H14N4, is non-planar with dihedral angles between the planes of the imidazole and phenyl-enedi-amine rings of 30.66 (4)° and between the planes of the phenyl-enedi-amine and N-phenyl rings of 56.63 (7)°. In the crystal, mol-ecules are connected by N-H⋯N hydrogen bonds, generating a chain extending along the b-axis direction. The crystal structure is also stabilized by C-H⋯π inter-actions between N-phenyl and imidazole rings and slipped π-π stacking inter-actions between imidazole rings [centroid-centroid distance = 3.516 (4) Å] giving an overall two-dimensional layered structure lying parallel to (010).
