Abstract
The structure of the title compound (23DMPBA), C(15)H(14)O(2), resembles those of phenyl benzoate (PBA), 3-methyl-phenyl benzoate (3MePBA), 2,6-dichloro-phenyl benzoate (26DC-PBA) and other aryl benzoates, with similar bond parameters. The dihedral angle between the benzene and benzoyl rings in 23DMPBA is 87.36 (6)°, compared with values of 55.7° in PBA, 79.61 (6)° in 3MePBA and 75.75 (10)° in 26DCPBA. The mol-ecules in 23DMPBA are packed into a chain-like structure in the direction of the a axis.Entities:

| 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. |
