2-Methyl-N-phenylbenzamide

B. T. Gowda, S. Foro, B. P. Sowmya and H. Fuess

Abstract top

In the structure of the title compound (NP2MBA), C14H13NO, the conformation of the C-O bond is syn to the ortho-methyl substituent in the benzoyl phenyl ring, while the N-H bond is anti to the ortho-methyl substituent. The structure of NP2MBA closely resembles that of 2-chloro-N-phenylbenzamide, with similar bond parameters. The dihedral angle between the phenyl and benzoyl rings is 88.05 (5)°. Molecules are linked into a chain through N-H...O hydrogen bonding.

Comment top

As part of a study of the substituent effects on the structures of benzanilides, in the present work, the structure of 2-methyl-N-(phenyl)benzamide (NP2MBA) has been determined (Gowda, et al., 2003; 2007; 2008). In the structure of NP2MBA,(Fig. 1), the conformation of the C—O bond is syn to the ortho-methyl substituent in the benzoyl phenyl ring, while the N—H bond is anti to the ortho-methyl substituent. The bond parameters in NP2MBA are similar to those in 2-chloro-N-(phenyl)-benzamide (Gowda, et al.,2003), 2-chloro-N-(2-chlorophenyl)-benzamide (Gowda, et al.,2007), N-(4-methylphenyl)-benzamide (Gowda, et al.,2008) and other benzanilides. The dihedral angle between the phenyl and benzoyl rings in NP2MBA is 88.05 (5)°. The packing diagram of NP2MBA molecules showing the hydrogen bonds N1—H1N···O1 (Table 1) involved in the formation of molecular chain is shown 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 NH atom was located in difference map with N—H = 0.88 (2) %A. The other H atoms were positioned with idealized geometry using a riding model with C—H = 0.95–0.98 Å A l l H atoms 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.
