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.
