The structure of the title compound, C14H12O2, resembles those of phenyl benzoate and 4-methylphenyl benzoate, with similar bond parameters. The two aromatic rings make a dihedral angle of 76.0 (1)°. The plane of the central —C(=O)—O— group is twisted by 9.4 (2)° out of the plane of the benzoyl ring, and by 83.3 (1)° out of the plane of the phenyl ring. The exhibits weak parallel stacking of the benzoyl rings, with an interplanar distance of 3.65 Å and an offset of 1.84 Å. The methyl group shows orientational disorder.

The title compound was prepared according to a literature method (Nayak & Gowda, 2009). The purity of the compound was checked by determination of its melting point. It was characterized by infrared and NMR spectra (Nayak & Gowda, 2009). Colorless single crystals of the title compound were obtained by slow evaporation of its ethanol solution.
All hydrogen atoms were placed in calculated positions with C–H distances 0.93 or 0.96 Å. The C14 methyl group shows orientational disorder in the hydrogen atom positions. The two sets of methyl hydrogen atoms were refined with equal occupancy. The Uiso(H) values were set at 1.2 Ueq(C-aromatic) or 1.5 Ueq(C-methyl).
In the present work, as a part of the study of the substituent effects on the crystal structures of aryl benzoates (Gowda et al., 2007a, b; 2008), the structure of phenyl-4-methylbenzoate (I) has been determined. The structure of (I) (Fig. 1) is similar to those of phenyl benzoate (II) (Adams & Morsi, 1976), 4-methylphenyl benzoate (III) (Gowda et al., 2007b), 4-methylphenyl 2-methylbenzoate (IV) (Gowda et al., 2008), 4-methylphenyl 4-methylbenzoate (V) (Gowda et al., 2007a) and other aryl benzoates. The two benzene rings make a dihedral angle of 76.0 (1)°, compared to the values of 55.7° for (II), 60.17 (7)° (III), 73.04 (8)° (IV) and 63.57 (5)° (V). The plane of the central –C(=O)–O– group in (I) is twisted 9.4 (2)° out of the plane of the benzoyl ring, and 83.3 (1)° out of the plane of the phenyl ring. The
exhibits weak parallel stacking of benzoyl rings, with interplanar distance of 3.65 Å and offset 1.84 Å. In the there are no classical hydrogen bonds. The molecules in the structure are packed into chains as viewed in the ac plane (Fig. 2).For preparation of the compound, see: Nayak & Gowda (2009).

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 the study of the substituent effects on the crystal structures of aryl benzoates (Gowda et al., 2007a, b; 2008), the structure of phenyl-4-methylbenzoate (I) has been determined. The structure of (I) (Fig. 1) is similar to those of phenyl benzoate (II) (Adams & Morsi, 1976), 4-methylphenyl benzoate (III) (Gowda et al., 2007b), 4-methylphenyl 2-methylbenzoate (IV) (Gowda et al., 2008), 4-methylphenyl 4-methylbenzoate (V) (Gowda et al., 2007a) and other aryl benzoates. The two benzene rings make a dihedral angle of 76.0 (1)°, compared to the values of 55.7° for (II), 60.17 (7)° (III), 73.04 (8)° (IV) and 63.57 (5)° (V). The plane of the central –C(=O)–O– group in (I) is twisted 9.4 (2)° out of the plane of the benzoyl ring, and 83.3 (1)° out of the plane of the phenyl ring. The crystal structure exhibits weak parallel stacking of benzoyl rings, with interplanar distance of 3.65 Å and offset 1.84 Å. In the crystal structure, there are no classical hydrogen bonds. The molecules in the structure are packed into chains as viewed in the ac plane (Fig. 2).
