摘要：
The asymmetric unit of the title compound, C21H18O3, contains two crystallographically independent molecules. The two molecules are linked into cyclic centrosymmetric dimers R-2(2)(8) by O-H center dot center dot center dot O hydrogen bonds. The dihedral angles between the naphthalene ring system and the benzene ring are 87.0 (8) and 84.4 (2)degrees in the two molecules. The crystal packing is stabilized by O-H center dot center dot center dot O, C-H center dot center dot center dot pi and pi-pi interactions [centroid-centroid distance = 3.664 (11) angstrom]. In one molecule, the mesityl ring is disordered over two positions [occupancy ratio 0.690 (3): 0.690 (3)].
