Abstract top

The structure of the title compound (26DCP4MeBA), C14H10Cl2O2, resembles those of phenyl benzoate (PBA), 2,6-dichlorophenyl benzoate (26DCPBA), 2,4-dichlorophenyl 4-methylbenzoate (24DCP4MeBA) and other aryl benzoates, with similar bond parameters. The dihedral angle between the benzene and benzoyl rings in 26DCP4MeBA is 77.97 (9)°, compared with values of 55.7 (PBA), 75.75 (10) (26DCPBA) and 48.13 (5)° (24DCP4MeBA). The molecules in the title compound are packed into zigzag chains in the bc plane.

Comment top

In the present work, as part of a study of the substituent effects on the structures of chemically and industrially significant compounds (Gowda et al., 2007a,b), the structure of 2,6-dichlorophenyl 4-methylbenzoate (26DCP4MeBA) has been determined. The structure of 26DCP4MeBA (Fig. 1) resembles those of phenyl benzoate (PBA) (Adams & Morsi, 1976), 2,6-dichlorophenyl benzoate (26DCPBA) (Gowda et al., 2007a), 2,4-dichlorophenyl 4-methyl benzoate (24DCP4MeBA) (Gowda et al., 2007b) and other aryl benzoates. The bond parameters in 26DCP4MeBA are similar to those in PBA, 26DCPBA, 24DCP4MeBA and other benzoates. The dihedral angle between the benzene and benzoyl rings in 26DCP4MeBA is 77.97 (9)°, compared to the values of 55.7° (PBA)(Adams & Morsi, 1976), 75.75 (10)° (26DCPBA)(Gowda et al., 2007a) and 48.13 (5)° (24DCP4MeBA)(Gowda et al., 2007b). The molecules in 26DCP4MeBA are packed into a zigzag structure with the dichlorophenyl ring being nearly orthogonal to the benzoyl ring (Fig. 2).

Experimental top

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 were obtained by slow evaporation of an ethanolic solution.

Refinement top

The H atoms were positioned with idealized geometry using a riding model (C—H = 0.93–0.96 Å) 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.
