(2,7-Dimeth­oxy­naphthalen-1-yl)(4-meth­oxy­phen­yl)methanone

In the mol­ecule of the title compound, C₂₀H₁₈O₄, the dihedral angle between the naphthalene ring system and the benzene ring is 81.74 (5)°. An inter­molecular C—H...O inter­action is formed between an H atom at the 6-position of the naphthalene ring and the O atom of the meth­oxy group at the 7-position.

(2,7-Dimeth­oxy­naphthalen-1-yl)(4-phen­oxy­phen­yl)methanone

In the title mol­ecule, C₂₅H₂₀O₄, the naphthalene and phen­oxy groups are oriented nearly perpendicular with respect to the benzene ring of the benzoyl group, with dihedral angles of 89.61 (5) and 86.13 (6)°, respectively. The crystal structure features C—H...O and C—H...π inter­actions.
