The conformation of the C=O bond in the title compound 2MP4MBA, C15H14O2, is anti to the ortho-methyl group in the phenoxy ring. The bond parameters in 2MP4MBA are similar to those in 3-methylphenyl 4-methylbenzoate (3MP4MBA), 4-methylphenyl 4-methylbenzoate (4MP4MBA) and other aryl benzoates. The dihedral angle between the two aromatic rings in 2MP4MBA is 73.04 (8)°.

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 for X-ray diffraction studies were obtained by slow evaporation of an ethanolic solution at room temperature.
The H atoms of the methyl groups were positioned with idealized geometry using a riding model with C—H = 0.96 Å. The other H atoms were located in difference map, and its positional parameters were refined freely [C—H = 0.87 (3)–1.05 (3) Å. All H atoms were refined with isotropic displacement parameters (Uiso(H) = 1.2 Ueq(CH) and 1.5Ueq(CH3))
To improve the values of R1, wR2, and GOOF, the bad three reflections (1 1 0 2 0 0 1 1 1) were omitted from the refinement.

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 part of a study of the substituent effects on the crystal structures of aryl benzoates (Gowda et al., 2007; 2008), the structure of 2-methylphenyl 4-methylbenzoate (2MP4MBA) has been determined. The conformation of the C=O bond in 2MP4MBA is anti to the ortho-methyl group in the phenolic benzene ring (Fig. 1). The bond parameters in 2MP4MBA are similar to those in 3-methylphenyl 4-methylbenzoate (3MP4MBA), 4-methylphenyl 4-methylbenzoate (4MP4MBA) (Gowda et al., 2007) and other aryl benzoates (Gowda et al., 2008). The dihedral angle between the benzene and benzoyl rings in 2MP4MBA is 73.04 (8)°, compared to the values of 56.82 (7)° in 3MP4MBA and 63.57 (5)° in 4MP4MBA. The packing diagram of molecules in the crystal structure is shown in Fig. 2.
