Keyword(s):
In the title compound, C20H17N3O [systematic name: 1-phenyl-3-{2-[(E)- (phenylmethylidene)amino]phenyl}urea], the middle benzene ring forms dihedral angles of 17.65 (17) and 29.48 (14)°, respectively, with the N- and C-bound phenyl rings, while the dihedral angle between the terminal rings is 46.53 (18)°. In the crystal, molecules are linkedviaN—H...O hydrogen bonds, forming helical supramolecular chains running parallel to thecaxisviaanR12(6) ring motif. The structure was refined as a two-component twin with a 0.966 (3):0.034 (3) domain ratio.
