Abstract top

The title benzamide derivative, C14H12ClNO2, crystallizes with two independent molecules in the asymmetric unit. Both are close to being planar, with dihedral angles between the two benzene rings of 11.92 (6) and 12.80 (7)°. In the crystal structure, N-H...O hydrogen bonds link molecules into chains along a. These interactions are augmented by C-H...O hydrogen bonds to form two-dimensional layers in the ac plane. Additional C-H...O interactions result in a three-dimensional network consisting of undulating rows along c. The crystal studied was an inversion twin with a 0.59 (3):0.41 (3) domain ratio.

Comment top

Benzanilides have important uses in organic synthesis (e.g. Zhichkin et al., 2007) and show biological activity (e.g. Igawa et al., 1999).

The title compound, (I), crystallized as an inversion twin in the crystal studied with two independent molecules, A and B, in the asymmetric unit. Bond distances and angles within the molecules are normal (Allen et al., 1987). Each molecule deviates slightly from planarity with dihedral angles between the two benzene rings of 11.92 (6)° for A and 12.80 (7)° for B.

In the crystal structure, N—H···O hydrogen bonds link molecules into chains along a (Table 1). These interactions are augmented by C—H···O hydrogen bonds to form two dimensional layers in the ac plane, Fig 2. Additional C—H···O interactions result in a three dimensional network consisting of undulating rows along c, Fig 3.

Experimental top

4-Chorobenzoyl chloride (5.4 mmol) in CHCl3 was treated with 3-methoxyaniline (21.6 mmol) under a nitrogen atmosphere at reflux for 4 h. Upon cooling, the reaction mixture was diluted with CHCl3 and washed consecutively with aqueous 1 M HCl and saturated aqueous NaHCO3. The organic layer was dried over anhydrous sodium sulfate and concentrated under reduced pressure. Crystallization of the residue from CHCl3 afforded the title compound (yield = 81%) as colourless needles: Analysis calculated. for C14H12ClNO2: C 64.25, H 4.62, N 5.35%; found: C 64.19, H 4.68, N 5.30%.

Refinement top

The crystal chosen was the smallest available without having to resort to potentially damaging cutting procedures.

The N-bound H atoms were located in a difference map and refined freely with isotropic displacememt parameters. The C-bound H atoms were geometrically placed (C—H = 0.95-0.98Å) and refined as riding with Uiso= 1.2Ueq(C) or 1.5Ueq(methyl C). The crystal studied was an inversion twin with a 0.59 (3):0.41 (3) domain ratio.

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.
