(2,7-Dimeth-oxy-naphthalen-1-yl)(phen-yl)methanone

Abstract

The asymmetric unit of the title compound, C(19)H(16)O(3), contains three independent conformers. Each of the three conformers has essentially the same feature of non-coplanar aromatic rings whereby the aroyl group at the 1-position of the naphthalene ring is twisted in a perpendicular manner to the naphthalene ring. The dihedral angles between the benzene ring planes and the naphthalene ring systems are 75.34 (7), 86.47 (7) and 76.55 (6)° in the three conformers. The crystal structure is stabilized by inter-molecular C-H⋯O hydrogen bonds.
