3,3'-Bis(quinolin-8-yl)-1,1'-[4,4'-methyl-enebis(4,1-phenyl-ene)]diurea.


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.
