In the title compound, C13H10ClNO, the meta-chloro group on the benzoyl ring is positioned syn to the C=O bond. The two aromatic rings make a dihedral angle of 88.5 (3)°. In the crystal, N—H⋯O hydrogen bonds link the mol­ecules into C(4) chains propagating in [010].

The amide and sulfonamide moieties are the constituents of many biologically significant compounds. As part of our studies on the substituent effects on the structures and other aspects of N-(aryl)-amides (Bhat & Gowda, 2000; Bowes et al., 2003; Gowda et al., 2008; Saeed et al., 2010, N-(aryl)-methanesulfonamides (Gowda et al., 2007), N-(aryl)-arylsulfonamides (Shetty & Gowda, 2005) and N-chloro-arylamides (Gowda & Weiss, 1994), in the present work, the crystal structure of 3-Chloro-N-(phenyl)benzamide (I) has been determined (Fig.1).

In (I), the meta-chloro group in the benzoyl ring is positioned syn to the C=O bond, while the N—H and C=O bonds in the C—NH—C(O)—C segment are anti to each other, similar to that observed in 3-Chloro-N-(3-chlorophenyl)-benzamide (II) (Gowda et al., 2008). Further, the two aromatic rings in (I) make the dihedral angle of 88.5 (3)°.

In the crystal structure, intermolecular N—H···O hydrogen bonds link the molecules into infinite chains running along the c-axis. Part of the crystal structure is shown in Fig. 2.

Experimental top

The title compound was prepared according to the method described by Gowda et al. (2003). 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.

Refinement top

All H atoms were visible in difference maps and then treated as riding atoms with C–H distances of 0.93Å (C-aromatic) and N—H = 0.86 Å. The Uiso(H) values were set at 1.2 Ueq(C-aromatic, N).

Experimental. CrysAlis RED (Oxford Diffraction, 2009) Analytical numeric absorption correction using a multifaceted crystal model based on expressions derived (Clark & Reid, 1995).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
