1-(4-Methoxyphenyl)-2-[4-(trifluoromethyl)phenyl]-1H-phenanthro[9,10-d]imidazole

Abstract

In the title compound, C29H19F3N2O, a phenanthroline-fused imidazole tetracyclic system, the fused benzene rings deviate slightly from the central ring and make dihedral angles with this ring of 3.47 (8) and 3.05 (8)°. The trifluoromethylphenyl ring is roughly coplanar with the phenanthroline-fused imidazole tetracyclic system [dihedral angle = 11.02 (6)°], while the methoxyphenyl ring is almost perpendicular [dihedral angle = 87.65 (6)°]. There are intramolecular C—H ...π interactions involving the methoxyphenyl ring and the central phenanthroline ring, as well as an intermolecular C—H...π interaction involving the phenanthroline ring. In addition, there is an intermolecular π–π interaction involving the central phenanthroline ring and the trifluoromethylphenyl ring [centroid–centroid distance = 3.685 (2) Å], as well as C—H...N interactions linking the molecules into dimers.
