The crystal structure of the title compound, C13H8Cl2O2, resembles those of 2,3-dichlorophenyl benzoate, 2,4-dimethylphenyl benzoate and other aryl benzoates, with similar bond parameters. The plane of central -C(=O)-O- group is inclined at the angle of 9.1 (2)° with respect to the benzoate ring. The two aromatic rings make a dihedral angle of 47.8 (1)°. In the crystal structure there are no classical hydrogen bonds. The molecules in the structure are packed into chains diagonally in the bc plane.
The title compound was prepared according to a literature method (Nayak & Gowda, 2009). The purity of the compound was checked by determining its melting point. It was characterized by recording its infrared and NMR spectra (Nayak & Gowda, 2009). Single crystals of the title compound were obtained by slow evaporation of its ethanol solution. The X-ray diffraction studies were made at room temperature.
H atoms were positioned geometrically and refined using a riding model with C—H distances of 0.93 Å, except for H atoms bound to C4 and C5, which were subject to the restraint on the C—H distance (set to 0.95 (4) Å). This measure improved the anisotropic displacement parameters of the atoms C4, C5 and enabled to remove the alert_C regarding the Hirshfeld-test. All H atoms were refined with Uiso(H) = 1.2 times Ueq(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. |

In the present work, as a part of studying the substituent effects on the crystal structures of aryl benzoates (Gowda et al., 2007, 2008, 2009), the structure of 2,4-dichlorophenyl benzoate has been determined. The structure (Fig. 1) is similar to those of 2,3-dichlorophenylbenzoate (Gowda et al., 2007), 2,4-dimethylphenyl benzoate (Gowda et al., 2008) and other aryl benzoates (Gowda et al., 2009). The two aromatic rings make a dihedral angle of 47.8 (1)°. The plane of the –C(=O)–O– group is inclined at an angle of 9.1 (2)° to the benzoate ring. In the crystal structure, there are no classical hydrogen bonds. The molecules in the structure are packed into chains as viewed down the bc plane (Fig. 2).
