The title compound, C(14)H(12)O(4), is an asymmetric substitution product of benzophenone. Both hy-droxy groups are orientated towards the O atom of the keto group. Intra-molecular as well as inter-molecular O-H⋯O hydrogen bonds can be observed in the crystal structure, with the latter connecting the mol-ecules into chains along the crystallographic b axis. C-H⋯O contacts [C⋯O = 3.3297 (18) Å] are also apparent. The closest centroid-centroid distance between two aromatic systems is 4.9186 (9) Å.
标题化合物C(14)H(12)O(4)是二苯甲酮的不对称取代产物。两个羟基均朝向酮基的O原子。在晶体结构中可观察到分子内和分子间的O-H⋯O氢键,后者将分子沿结晶学b轴连接成链。C-H⋯O接触[C⋯O = 3.3297 (18) Å]也很明显。两个芳香体系之间最接近的质心-质心距离为4.9186 (9) Å。
