Abstract: In the title compound, C₄₀H₃₂Cl₂O₄, the two chlorobenzene rings are in syn orientations with respect to the naphthalene ring system and make dihedral angles of 57.12 (6) and 85.74 (6)° with it. The benzene rings of the benzyloxy group make dihedral angles of 75.34 (6) and 83.95 (7)°, with the naphthalene ring system. In the crystal, the molecules are linked by intermolecular C-HCl interactions between the methylene H atoms of the benzyloxy group and the Cl atoms in adjacent molecules. Furthermore, centrosymmetrically related molecules are linked into dimeric units by pairs of C-H [pi] interactions.
