3,3'-Di-tert-butyl-1,1'-[1,3-phenyl-enebis(methyl-ene)]diurea.

ABSTRACT: The title compound, C(18)H(30)N(4)O(2), contains two tert-butyl urea groups, each connected to a benzene ring though a methyl-ene group. One of the groups occupies a position almost normal to the aromatic plane with a C-N-C-C torsion angle of -94.4?(4)°, while the other is considerably twisted from the ring with a C-N-C-C torsion angle of -136.1?(4)°. In the crystal, pairs of mol-ecules are connected to each other, forming centrosymmetric dimers in which two NH groups of one mol-ecule act as hydrogen-bond donors to one carbonyl O atom of the other mol-ecule. The dimers are linked into sheets parallel to (100) by N-H?O hydrogen bonds involving the remaining N-H and C=O groups.

Project description: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.
