Abstract: The title compound, C33H26N6O2, contains two 3-(quinolin-8-yl)urea groups linked to a diphenylmethane. The asymmetric unit contains two molecules, A and B. Each quinoline plane is essentially parallel to the attached urea unit [dihedral angles = 8.97 (18) and 8.81 (19) in molecule A and 18.47 (18) and 4.09 (19)° in molecule B]. The two benzene rings are twisted, making dihedral angles of 81.36 (8)° in A and 87.20 (9)° in B. The molecular structures are stabilized by intramolecular N-H...N hydrogen bonds. In the crystal, each urea O atom is involved in two N-H...O hydrogen bonds, generating two interpenetrating three-dimensional sets of molecules.
