title: Crystal structure of 3-[4-(1H-imidazol-1-yl)phen-yl]-2-(4-nitro-phen-yl)prop-2-ene-nitrile.
abstract: In the title compound, C18H12N4O2, which has a delocalized D-π-A electronic structure, the dihedral angles between the central benzene ring and the planes of the pendant imidazole and nitro-benzene rings are 37.65 (9) and 4.96 (7)°, respectively. In the centrosymmetric crystal structure, mol-ecules are linked by weak C-H⋯O inter-actions, generating [001] C(6) chains.
