1-{(E)-[3-(1H-Imidazol-1-yl)-1-phenylpropylidene]amino}-3-(2-methylphenyl)urea

Abstract

In the title compound, C20H21N5O, the conformation about the imine bond [1.289 (3) Å] is E. Overall, the mol­ecule is disk-shaped with the imidazole ring located above the remainder of the mol­ecule and with the dihedral angles of 10.97 (15) and 12.11 (15)°, respectively, between the imidazole ring and the phenyl and methyl­benzene rings; the dihedral angle between the aromatic rings is 8.17 (14)°. Within the urea unit, the N—H atoms are anti to each other and one of the N—H atoms forms an intra­molecular N—H⋯N hydrogen bond. Helical supra­molecular chains along [001] are formed via N—H⋯N(imidazole) hydrogen bonds in the crystal structure. These are connected into a three-dimensional architecture by C—H⋯O(carbon­yl) and C—H⋯π inter­actions.
