Abstract
The structure of the title compound (4BPBA), C(13)H(9)BrO(2), is similar to that of phenyl benzoate (PBA), 4-methyl-phenyl benzoate (4MePBA) and 4-methoxy-phenyl benzoate, with somewhat different bond parameters. The dihedral angle between the phenyl and benzoyl rings in 4BPBA is 58.43 (17)°, compared with values of 55.7° in PBA and 60.17 (7)° in 4MPBA. The mol-ecules in the title compound are packed into infinite chains in the a-axis direction.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. |
