The structure of the title compound (4CP4CBA), C13H8Cl2O2, resembles those of 4-methylphenyl 4-chlorobenzoate (4MP4CBA), 4-chlorophenyl 4-methylbenzoate (4CP4MBA) and 4-methylphenyl 4-methylbenzoate (4MP4MBA), with similar bond parameters. The dihedral angle between the two benzene rings in 4CP4CBA is 47.98 (7)°, compared with 51.86 (4)° in 4MP4CBA, 63.89 (8)° in 4CP4MBA and 63.57 (5)° in 4MP4MBA. In the molecules are linked into helical chains running along the b axis by C—H—O hydrogen bonds.

The title compound was prepared according to a literature method (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 of the title compound used in X-ray diffraction studies were obtained by slow evaporation of its ethanol solution.
H atoms were located in a difference map and their positional parameters were refined [C-H = 0.90 (3)–0.97 (3) Å] with Uiso(H) = 1.2Ueq(C).

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 solid state structures of aryl benzoates (Gowda et al., 2007; Gowda, Foro et al., 2008; Gowda, Svoboda et al., 2008), the crystal structure of 4-chlorophenyl 4-chlorobenzoate (4CP4CBA) has been determined. The structure (Fig. 1) is similar to those of 4-methylphenyl 4-chlorobenzoate (4MP4CBA) (Gowda, Svoboda et al., 2008), 4-chlorophenyl 4-methylbenzoate (4CP4MBA) (Gowda, Foro et al., 2008) and 4-methylphenyl 4-methylbenzoate (4MP4MBA) (Gowda et al., 2007). The bond parameters in 4CP4CBA are similar to those in afore mentioned 4MP4CBA, 4CP4MBA, 4MP4MBA and other aryl benzoates (Gowda et al., 2007; Gowda, Foro et al., 2008; Gowda, Svoboda et al., 2008). The dihedral angle between the benzene and benzoyl rings in 4CP4CBA is 47.98 (7)°, compared to the values of 51.86 (4)° in 4MP4CBA, 63.89 (8)° in 4CP4MBA and 63.57 (5)° in 4MP4MBA.
In the crystal structure, the molecules are linked into helical chains (Fig. 2) running along the b axis by C—H—O hydrogen bonds (Table 1).
