The conformation of the N—H bond in the structure of the title compound, C14H12ClNO, is anti to the meta-chloro substituent in the aniline ring, while the C=O bond is syn to the ortho-methyl substituent in the benzoyl ring. The conformations of the N—H and C=O bonds are anti to each other, similar to those observed in 2-methyl-N-(3-methyl­phen­yl)benzamide (N3MP2MBA). The –NHC(=O)– group makes a dihedral angle of 55.8 (7)° with the benzoyl ring, while the angle between the benzoyl and aniline rings is 37.5 (1)°; the respective values for N3MP2MBA are 55.2 (7) and 36.2 (1)°. N—H...O hydrogen bonds link the mol­ecules into infinite chains running along the c axis.

Comment top

In the present work, the structure of 2-methyl-N-(3-chlorophenyl)- benzamide (N3CP2MBA) has been determined as part of substituent effect studies on the solid state structures of benzanilides (Gowda et al., 2003; Gowda et al. (2008a, 2008b). The conformation of the N—H bond in N3CP2MBA (Fig. 1) is anti to the meta-chloro substituent in the aniline ring, while the C=O bond is syn to the ortho-methyl substituent in the benzoyl ring and the conformations of the N—H and C=O bonds are anti to each other, identical to that observed in 2-methyl-N-(3-methylphenyl)-benzamide (N3MP2MBA). The bond parameters in N3CP2MBA are similar to those in 2-methyl-N-(phenyl)-benzamide (Gowda et al., 2008a), N3MP2MBA (Gowda et al., 2008b) and other benzanilides (Gowda et al., 2003). The amide group, –NHCO– makes a dihedral angle of 55.8 (7)° with the benzoyl ring, while that between benzoyl and aniline rings is 37.5 (1)°, compared to the respective values of 55.2 (7)° and 36.2 (1)° for N3MP2MBA. The packing diagram of N3CP2MBA showing the hydrogen bonds N1—H1N···O1 (Table 1) is given in Fig. 2.

Experimental top

The title compound was prepared according to the literature method (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. Single crystals of the title compound were obtained from an ethanolic solution and used for X-ray diffraction studies at room temperature.

Refinement top

The H on N1 was located in difference map and its position freely refined. The other H atoms were positioned with idealized geometry using a riding model with C—H = 0.93–0.96 Å and were refined with isotropic displacement parameters (set to 1.2 times of the Ueq of the parent atom).

Special details top

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.
