1,2-Bis(benz-yloxy)-1,2-bis-(4-chloro-phen-yl)-3,8-dimeth-oxy-acenaphthene.

ABSTRACT

In the title compound, C(40)H(32)Cl(2)O(4), the two chloro-benzene 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 benz-yloxy group make dihedral angles of 75.34 (6) and 83.95 (7)°, with the naphthalene ring system. In the crystal, the mol-ecules are linked by inter-molecular C-H⋯Cl inter-actions between the methyl-ene H atoms of the benz-yloxy group and the Cl atoms in adjacent mol-ecules. Furthermore, centrosymmetrically related mol-ecules are linked into dimeric units by pairs of C-H⋯π inter-actions.
