摘要：

The title compound, C(33)H(26)N(6)O(2), 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)degrees in molecule B]. The two benzene rings are twisted, making dihedral angles of 81.36 (8)degrees in A and 87.20 (9)degrees in B. The molecular structures are stabilized by intramolecular N-H center dot center dot center dot N hydrogen bonds. In the crystal, each urea O atom is involved in two N-H center dot center dot center dot O hydrogen bonds, generating two interpenetrating three-dimensional sets of molecules.
