چکیده
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.
