(2-Hy-droxy-7-meth-oxy-naphthalen-1-yl)(4-methyl-phen-yl)methanone.

ABSTRACT: In the title compound, C(19)H(16)O(3), an intra-molecular O-H?O=C hydrogen bond is formed between the hy-droxy and carbonyl groups on the naphthalene ring system, resulting in an S(6) ring. The angles between the C=O bond vector and the least-squares planes of the naphthalene ring system and the benzene ring are 27.63?(6) and 47.99?(7)°, respectively. The dihedral angle between the latter planes is 61.39?(5)°. In the crystal, two mol-ecules are connected by pairs of inter-molecular O-H?O=C hydrogen bonds, forming centrosymmetric dimers with an R(2) (2)(4) graph-set motif. The mol-ecular packing features C-H?? interactions.
