title: [2,7-Dimeth-oxy-8-(4-meth-oxy-benzo-yl)naphthalen-1-yl](4-meth-oxy-phen-yl)methanone chloro-form monosolvate.
abstract: In the title compound, C28H24O6·CHCl3, the two 4-meth-oxy-benzoyl groups at the 1- and 8-positions of the naphthalene ring system are aligned almost anti-parallel, the benzene rings making a dihedral angle of 25.76 (7)°. The naphthalene ring system makes dihedral angles of 72.51 (7) and 73.33 (7)° with the benzene rings. In the crystal, the naphthalene mol-ecules are linked by C-H⋯O inter-actions, forming a helical chain along the b-axis direction. A C-H⋯Cl inter-action is also observed between the aroylated naphthalene and chloro-form mol-ecules. The chloro-form mol-ecule is disordered over two positions with site occupancies of 0.478 (5) and 0.522 (5).
