(Received 22 November 2011; accepted 25 November 2011; online 30 November 2011)

In the title compound, C16H17NO, the two aromatic rings make a dihedral angle of 5.9 (2)°, while the central amide core –NH—C(=O)– is twisted by 44.0 (3) and 47.1 (3)° out of the planes of the 2,3-dimethyl­phenyl and 2-methyl­phenyl rings, respectively. In the crystal, N—H⋯O hydrogen bonds link the mol­ecules into infinite chains running along the b axis.

Comment top

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 (Bowes et al., 2003; Gowda et al., 2000; Saeed et al., 2010), N-(aryl)-methanesulfonamides (Jayalakshmi & Gowda, 2004), N-(aryl)-arylsulfonamides (Shetty & Gowda, 2005) and N-chloro-arylsulfonamides (Gowda et al., 1996), in the present work, the crystal structure of N-(2,3-dimethylphenyl)-2-methylbenzamide (I) has been determined (Fig. 1).

In (I), the two aromatic rings make the dihedral angle of 5.9 (2)°, while the central amide core –NH—C(=O)– is twisted by 44.0 (3) ° and 47.1 (3)° out of the planes of the 2,3-dimethylphenyl and 2-methylphenyl rings, respectively.

Further, the ortho-methyl group in the benzoyl ring is positioned syn to the C=O bond and so also the ortho- and meta- methyl groups in the anilino ring to the N—H bond, while the N—H and C=O bonds in the C—NH—C(O)—C segment are anti to each other.

In the crystal structure, intermolecular N—H···O hydrogen bonds link the molecules into infinite chains running along the b-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. Plate like colourless single crystals of the title compound 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 hydrogen atoms except amide H atom were placed in calculated positions with C–H distances in the range 0.93–0.96 Å and constrained to ride on their parent atoms. The amide H atom was found in a difference map and was refined with the N—H distance restrained to 0.86 (3) Å. The Uĩso~(H) values were set at 1.2Ueq(C-aromatic, N) or 1.5Ueq(C-methyl). In the absence of significant anomalous scattering, the absolute structure could not be reliably determined and then the Friedel pairs were merged and any references to the Flack parameter were removed.

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.
