1-(4-Chloro-benzo-yl)-2,7-dimethoxy-naphthalene.

In the title compound, C(19)H(15)ClO(3), the dihedral angle between the naphthalene ring system and the benzene ring is 72.06 (7)°. The 4-chloro-phenyl group and the carbonyl group are almost coplanar. An inter-molecular C-H⋯O hydrogen bond is formed between an H atom of the 4-chloro-phenyl group and the O atom of one meth-oxy group, forming a zigzag chain along the a axis.
