1-{(E)-[3-(1H-Imidazol-1-yl)-1-phenyl-propyl-idene]amino}-3-(2-methyl-phen-yl)urea.
In the title compound, C(20)H(21)N(5)O, the conformation about the imine bond [1.289 (3) Å] is E. Overall, the mol-ecule is disk-shaped with the imidazole ring located above the remainder of the mol-ecule and with the dihedral angles of 10.97 (15) and 12.11 (15)°, respectively, between the imidazole ring and the phenyl and methyl-benzene 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 intra-molecular N-H⋯N hydrogen bond. Helical supra-molecular 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(carbon-yl) and C-H⋯π inter-actions.
