(Received 8 June 2008; accepted 24 June 2008; online 28 June 2008)

The conformations of the N—H and C=O bonds in the structure of the title compound (N26DMP4CBA), C₁₅H₁₄ClNO, are anti to each other, similar to that observed in N-phenylbenzamide, N-(3,4-dimethylphenyl)benzamide, N-(2,6-dichlorophenyl)benzamide and other benzanilides. There are three molecules in the asymmetric unit of N26DMP4CBA. The central amide group is tilted with respect to the benzoyl ring by 45.2 (1)° in molecule 1, 21.2 (2)° in molecule 2 and 14.9 (2)° in molecule 3. The dihedral angles between the benzoyl and aniline rings are 39.9 (1), 51.0 (1) and 86.3 (3)° in molecules 1, 2 and 3, respectively. Intermolecular N—H⋯O hydrogen bonds link the molecules into infinite chains running along the [101] direction. One xylyl group is disordered over two positions; the site occupancy factors are ca 0.6 and 0.4.

Comment top

In the present work, the structure of N-(2,6-dimethylphenyl)- 4-chlorobenzamide (N26DMP4CBA) has been determined to study the effect of substituents on the solid state geometries of benzanilides (Gowda et al., 2003, 2008a,b).

The conformations of the N—H and C=O bonds in N26DMP4CBA (Fig.1) are anti to each other, similar to that observed in N-(phenyl)-benzamide(NPBA)(Gowda et al., 2003), N-(3,4-dimethylphenyl)-benzamide (Gowda et al., 2008a), N-(2,6-dichlorophenyl)-benzamide and other benzanilides (Gowda et al., 2008b), with similar bond parameters. The amide group –NHCO– forms the dihedral angle of 45.2 (1)° in molecule 1, 21.2 (1)° in molecule 2, and 14.9 (2)° in molecule 3, with the benzoyl benzene ring. The dihedral angles between the benzoyl and aniline benzene rings are 39.9 (1)°, 51.0 (1)° and 86.3 (3)° in the molecule 1, 2 and 3, respectively.

The intermolecular N—H···O hydrogen bonds link the molecules into infinite chains running along the [101] direction (Table 1).

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.

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.
