✦ Synopsis

The asymmetric unit of the title compound, C 14 H 10 Cl 2 N 2 O, comprises two independent molecules, in which the dihedral angles between the terminal phenyl and substituted benzene rings are 21.28 (10) and 39.60 (12) . N-HÁ Á ÁO, C-HÁ Á ÁO and C-HÁ Á ÁCl hydrogen bonds stabilize the conformations of the molecules and also stabilize the structure in the solid state.
