The asymmetric unit of the title compound, C(23)H(16)O(2), contains two independent mol-ecules in which the dihedral angles between the anthracene ring system and the benzene ring are 73.0 (3) and 73.3 (3)°. In both independent mol-ecules, the hy-droxy group is involved in an intra-molecular O-H⋯O hydrogen bond. The crystal packing is stabilized by π-π inter-actions [centroid-centroid distances = 3.6518 (9), 3.7070 (9) and 3.7632 (9) Å] and weak inter-molecular C-H⋯O hydrogen bonds.
标题化合物C(23)H(16)O(2)的不对称单元包含两个独立分子,其中蒽环系统与苯环之间的二面角分别为73.0 (3)°和73.3 (3)°。在两个独立分子中,羟基均参与分子内O-H⋯O氢键。晶体堆积通过π-π相互作用[质心-质心距离 = 3.6518 (9)、3.7070 (9)和3.7632 (9) Å]以及弱分子间C-H⋯O氢键得以稳定。
