N-(4-Chloro­phen­yl)benzamide

The structure of the title compound, C₁₃H₁₀ClNO, resembles those of N-phen­ylbenzamide, N-(2-chloro­phenyl)­benzamide and other benzanilides, with similar bond parameters. The amide group –NHCO– makes a dihedral angle of 29.95 (9)° with the benzoyl ring, while the benzoyl and aniline rings form a dihedral angle of 60.76 (3)°. The structure shows both intra- and inter­molecular hydrogen bonding. The mol­ecules are linked by N—H...O hydrogen bonds into chains running along the [100] direction.

S1. Comment

In the present work, the structure of N-(4-chlorophenyl)benzamide (N4CPBA) has been determined to study the effect of substituents on the structures of benzanilides (Gowda et al., 2003, 2007, 2008).

The structure of N4CPBA (Fig.1) is similar to those of N-(phenyl)benzamide, N-(2-chlorophenyl)benzamide, N-(3-chlorophenyl)benzamide and N-(4-methylphenyl)benzamide and other benzanilides (Gowda et al., 2003, 2007, 2008). The amide group –NHCO– forms dihedral angle of 29.95 (9)° with the benzoyl ring, while the two benzene rings (benzoyl and aniline rings) form dihedral angle of 60.76 (3)°. Part of the structure of N4CPBA as viewed down the b axis and showing infinite molecular chains in the [100] direction is shown in Fig. 2. The chains are generated by the intermolecular N—H···O hydrogen bonds (Table 1).

S2. Experimental

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.

S3. Refinement

H atoms attached to C atoms were placed in calculated positions and subsequently treated as riding with C—H distance 0.93 Å. H atom of the amide group was refined with the N—H distance restrained to 0.86 (4) Å. The U_iso(H) values were set at 1.2 U_eq(C,N).

Special details

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.
