The conformation of the C=O bond in the title compound, C14H11ClO2, is anti to the Cl atom, similar to what was observed in 2-methylphenyl 4-methylbenzoate. The dihedral angle between the two aromatic rings is 59.36 (7)°.

The title compound was prepared according to a method of Nayak & Gowda (2008). The purity of the compound was checked by determining its melting point. It was characterized by recording its infrared and NMR spectra (Nayak & Gowda, 2008). Single crystals used in X-ray diffraction studies were obtained by slow evaporation of ethanolic solution of the title compound.
The H atoms were positioned with idealized geometry and refined using a riding model with Caromatic—H = 0.93Å or Cmethyl—H = 0.96 Å and with isotropic displacement parameters set to 1.2 Ueq(C) or 1.5Ueq(Cmethyl). The methyl group was allowed to rotate but not to tip.

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. |

As part of a study of the substituent effects on the crystal structures of aryl benzoates (Gowda et al., 2008a, 2008b, 2008c), in the present work, the structure of 2-chlorophenyl 4-methylbenzoate (2CP4MBA) has been determined. The conformation of the C=O bond in 2CP4MBA is anti to the ortho-chloro group in the phenolic benzene ring (Fig. 1), similar to what is observed in 2-methylphenyl 4-methylbenzoate (2MP4MBA) (Gowda et al., 2008c). The dihedral angle between the benzene and benzoyl rings in 2CP4MBA is 59.36 (7)°, compared with the values of 71.75 (7)° in 3CP4MBA (Gowda et al., 2008a), 63.89 (8)° in 4CP4MBA (Gowda et al., 2008b) and 73.04 (8)° in 2MP4MBA (Gowda et al., 2008c). Further, the bond parameters in 2CP4MBA are similar to those in 2MP4MBA and other aryl benzoates (Gowda et al., 2008a, b, c). The packing diagram is shown in Fig. 2.
