3-Chloro­phenyl 4-methyl­benzoate

The crystal structure of the title compound 3CP4MBA, C₁₄H₁₁ClO₂, resembles those of 3-methyl­phenyl 4-methyl­benzoate (3MP4MBA), 4-methyl­phenyl 4-methyl­benzoate (4MP4MBA), 4-methyl­phenyl 4-chloro­benzoate (4CP4MBA) and other aryl benzoates with similar bond parameters. The dihedral angle between the benzene rings in 3CP4MBA is 71.75 (7)°, compared with 56.82 (7)° in 3MP4MBA and 63.57 (5)° in 4MP4MBA. In the crystal structure, the mol­ecules are aligned with their long axis approximately along the [101] direction and stacked along the c axis.

S1. Comment

In the present work, as part of a study of the substituent effects on the solid state geometries of aryl benzoates (Gowda et al., 2007, 2008), the structure of 3-chlorophenyl 4-methylbenzoate (3CP4MBA) has been determined. The structure of 3CP4MBA (Fig. 1) is similar to those of 3-methylphenyl 4-methyl- benzoate (3MP4MBA), 4-methylphenyl 4-methylbenzoate (4MP4MBA), 4-methylphenyl 4-chlorobenzoate (4MP4CBA) and other aryl benzoates (Gowda et al., 2007, 2008). The bond parameters in 3CP4MBA are similar to those in 3MP4MBA, 4MP4MBA, 4CP4MBA and other aryl benzoates. The dihedral angle between the benzene and phenyl rings in 3CP4MBA is 71.75 (7)°, compared to the values of 56.82 (7)° in 3MP4MBA and 63.57 (5)° in 4MP4MBA. In the crystal structure, the molecules are elongated approximatelly along the [101] direction and stacked along the c axis (Fig. 2).

S2. Experimental

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 its ethanolic solution.

S3. Refinement

H atoms (for CH) were located in difference map and refined [ C-H = 0.89 (2) -0.98 (2) Å; U_iso(H) = 0.067-0.079 Ų]. The methyl H atoms were positioned geometrically, with C-H= 0.96 Å, and constrained to ride on the parent atom, with U_iso(H) = 1.2U_eq(C).

Special details

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 > 2sigma(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.
