RESUMO
In the title compound, C28H24O4, the benzoyl groups at the 1- and 8-positions of the naphthalene ring system are aligned almost anti-parallel, and the benzene rings make a dihedral angle of 20.03â (7)°. The dihedral angles between the benzene rings and the naphthalene ring system are 68.42â (5) and 71.69â (5)°. In the crystal, adjacent mol-ecules are linked via C-Hâ¯O hydrogen bonds, forming chains propagating along [100].
RESUMO
In the title compound, C(23)H(18)O(3), the dihedral angle between the two naphthalene ring systems is 78.02â (3)°. The bridging carbonyl C-C(=O)-C plane makes a dihedral angle of 70.56â (5)° with the naphthalene ring system in the 2,7-dimeth-oxy-naphthalene moiety and a dihedral angle of 11.53â (5)° with the naphthalene ring system in the naphthoyl group. In the crystal, adjacent mol-ecules are linked via C-Hâ¯π inter-actions, forming chains along [010].
