(Received 28 September 2012; accepted 2 October 2012; online 6 October 2012)

In the title compound, C14H12ClNO2, the mean plane through the amide group [–N—C=O–] forms dihedral angles of 27.55 (8) and 31.94 (7)° with the meth­oxy- and chloro-substituted benzene rings, respectively. The dihedral angle between the benzene rings is 59.24 (4)°. In the crystal, N—H⋯O and weak C—H⋯O hydrogen bonds link the mol­ecules into chains along the a axis.

Comment top

Aromatic amides have been utilized as versatile fragments to construct frameworks that have numerous functions such as molecular recognition, conformational switching, and biological activities which include in vitro xanthine oxidase (XO), tyrosinase and melanin production inhibitory activity. Further, benzanilides and their metal complexes have also been known for their marked biological activities such as antifungal,antibacterial and genotoxic effect (Chen et al., 2011). Globally, multidrug-resistant bacteria are a major health problem leading to severe consequences; anilides have shown antimycobacterial activity against classical mycobacterium tuberculosis (El Rayes et al., 2008), thiobenzanilides also belong to a group of biologically active compounds possessing antimicobacterial activities. In addition, N-substituted carboxamide isothiazoles (Regiec et al., 2006) produced a remarkable immunotropic, antiviral and anti-inflammatory activities, N-acylamino benzamides (Kuroda et al., 2006), constitute an important class of potent insecticides.

The molecular structure of the title compound (I) is shown in Fig. 1. All bond lengths and angles are normal and correspond to those observed in the related structures (Gowda et al., 2008; Saeed et al., 2008). The amide group [–N—C═O–] forms dihedral angles of 27.55 (8) and 31.94 (7)° with methoxy-substituted benzene [C1-C6] and chloro-substitued benzene [C9-C14] rings, respectively. The two benzene rings are twisted by 59.24 (4)° with respect to each other. In the crystal, N1—H1···O1i and C14—H14A···O1i hydrogen bonds link the molecules into chains along the a axis (Fig. 2) (Table 1).

Experimental top

To a mixture of 4-chloroaniline (0.127 g, 1 mmol) and aq. sodium hydroxide solution (10%, 20 ml) in a round bottom flask (50 ml), 4-methoxybenzoyl chloride (0.170 g, 1 mmol) was added in portions during stirring at room temperature. After the complete addition of 4-methoxybenzoyl chloride, the reaction mixture was further stirred for 30 minutes and then poured into ice-cold water (25 ml). It was further stirred for 10 min. and filtered. Finally, the product was obtained after drying followed by crystallization from ethanol (0.224 g, 86%) to give X-ray quality crystals.

Refinement top

The H atom bonded to the N atom was located in a difference map and refined independently with an isotropic displacement parameter. Other H atoms were positioned geometrically and were treated as riding on their parent C atoms, with C—H distances of 0.93–0.96 Å and with with Uiso(H) = 1.2Ueq(C) or 1.5Ueq(methyl C).

Experimental. CrysAlis PRO, Oxford Diffraction Ltd., Version 1.171.34.40 (release 27–08-2010 CrysAlis171. NET) (compiled Aug 27 2010,11:50:40) Empirical absorption correction using spherical harmonics, implemented in SCALE3 ABSPACK scaling algorithm.

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.
