title: 1-(3-Chloro-phen-yl)-3-(4-nitro-phen-yl)urea.
abstract: In the title compound, C(13)H(10)ClN(3)O(3), prepared by the reaction of 1-chloro-3-isocyanato-benzene with 4-nitro-benzenamine, the two substituent benzene rings are roughly coplanar [inter-ring dihedral angle = 8.70 (7)°]. In the crystal, mol-ecules make cyclic inter-molecular associations through two urea-nitro N-H⋯O hydrogen bonds, forming a chain structure [give chain direction] in which there are also weak inter-molecular C-H⋯Cl inter-actions. The urea O atom has only intra-molecular aromatic ring C-H⋯O associations.
