The structure of the title compound (23DCPBA), C13H8Cl2O2, resembles that of phenyl benzoate (PBA), 2,6-dichloro­phenyl benzoate (26DCPBA) and 3,4-dichloro­phenyl benzoate (34DCPBA), with similar geometric parameters. The dihedral angle between the phenyl and benzoyl rings in 23DCPBA is 50.16 (7)°, compared to the value of 55.7° for PBA, 75.75 (10)° for 26DCPBA and 53.77 (5)° for 34DCPBA.

Comment top

In the present work, as part of a study of the substituent effects on the structures of aryl benzoates (Gowda, Foro, Babitha & Fuess, 2007a, b, c; Gowda, Foro, Nayak & Fuess, 2007a, Gowda, Foro, Nayak & Fuess, 2007b), the structure of 2,3-dichlorophenyl benzoate (23DCPBA) has been determined. The structure of 23DCPBA (Fig. 1) is similar to those of phenyl benzoate (PBA) (Adams & Morsi, 1976); 2,6-dichlorophenyl benzoate (26DCPBA)(Gowda et al., 2007c); 3,4-dichlorophenyl benzoate (34DCPBA)(Gowda, Foro, Babitha & Fuess, 2007b) and other aryl benzoates (Gowda, Foro, Babitha & Fuess, 2007a; Gowda, Foro, Nayak & Fuess, 2007a, b). The bond parameters in 23DCPBA are similar to those in PBA, 26DCPBA, 34DCPBA and other aryl benzoates. A packing diagram is shown in Fig. 2.

Experimental top

The title compound was prepared according to a literature method (Nayak & Gowda, 2007). The purity of the compound was checked by determining its melting point. It was characterized by recording its infrared and NMR spectra (Nayak & Gowda, 2007). Single crystals of the title compound were obtained by slow evaporation of an ethanolic solution and used for X-ray diffraction studies at room temperature.

Refinement top

The H atoms were located in difference map, and their positional parameters were refined with Uiso = 1.2 Ueq of the parent atom.

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.
