Abstract

The title compound, C(33)H(26)N(6)O(2), contains two 3-(quinolin-8-yl)urea groups linked to a diphenyl-methane. The asymmetric unit contains two mol-ecules, 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 inter-penetrating three-dimensional sets of mol-ecules.
