1-(2-Chloro-benzo-yl)-3-[4-(trifluoro-meth-oxy)phen-yl]urea.

ABSTRACT

The title compound, C(15)H(10)ClF(3)N(2)O(3), is considered to belong to a fourth generation of insecticides with properties such as high selectivity, low acute toxicity for mammals and high biological activity. The dihedral angle between the two benzene rings is 59.3 (2)°. Intra-molecular C-H⋯O and N-H⋯O hydrogen bonds are observed. Inter-molecular N-H⋯O hydrogen bonding generates a centrosymmetric dimer. The F atoms are disordered over two positions; the site occupancy factors are 0.52 and 0.48.
