Abstract: The asymmetric unit of the title compound, C23H18O3, contains two independent molecules (A and B). Each molecule has essentially the same conformation (r.m.s. deviation of fitted molecules = 0.173 Å) with the aromatic rings twisted in a near perpendicular manner. The dihedral angles between the two naphthalene ring systems are 79.07 (4) and 88.19 (4)° in the two independent molecules. In the crystal, the A molecules are connected by C-H...O interactions, forming chains along the b-axis direction. Further C-H...O interactions between the H atoms of the methoxy group and the O atoms of the carbonyl units link the A and B molecules, forming a three-dimensional network.
