3-Chloro-N-(2-chlorophenyl)benzamide

In the title compound, C13H9Cl2NO, the meta-Cl atom in the benzoyl ring is positioned anti to the C=O bond, while the ortho-Cl atom in the aniline ring is positioned syn to the N—H bond. The two aromatic rings are almost coplanar, making a dihedral angle of 4.73 (5)°. The crystal structure is stabilized by N—H⋯O hydrogen bonds, which link the molecules into chains along the b axis.

The crystal structure is stabilized by N-HÁ Á ÁO hydrogen bonds, which link the molecules into chains along the b axis.
In (I), the meta-Cl atom in the benzoyl ring is positioned anti to the C=O bond, while the ortho-Cl group in the anilino ring is positioned syn to the N-H bond, the N-H and C=O bonds in the C-NH-C(O)-C segment being anti to each other.
In the crystal structure, intermolecular N-H···O hydrogen bonds link the molecules into infinite chains running along the a-axis. Part of the crystal structure is shown in Fig. 2.

Experimental
The title compound was prepared according to the method described by Gowda et al. (2008). The purity of the compound was checked by determining its melting point. It was characterized by recording its infrared and NMR spectra.
Rod like colorless single crystals of the title compound used in X-ray diffraction studies were obtained by slow evaporation of an ethanol solution of the compound (0.5 g in about 30 ml of ethanol) at room temperature.
