(4-Chlorophenyl)(2-hydroxy-7-methoxynaphthalen-1-yl)methanone

Abstract

The title compound, C18H13ClO3, has an intramolecular O-H center dot center dot center dot O = C hydrogen bond between the carbonyl group and the hydroxy substituent on the naphthalene ring system. The angle between the C = O bond plane and the naphthalene ring system is relatively small [20.96 (8)degrees]. The angle between the benzene ring and the carbonyl group is rather large [35.65 (9)degrees] compared to that in an analogous compound [3.43 (11)degrees] having a methoxy group instead of a hydroxy substituent.
