Methyl 4-(2,7-dimeth-oxy-1-naphtho-yl)benzoate.

ABSTRACT: In the title compound, C(21)H(18)O(5), the dihedral angle between the naphthalene ring system and the benzene ring is 86.65?(6)°. The bridging carbonyl C-C(=O)-C plane makes dihedral angles of 83.57?(7) and 20.21?(8)°, respectively, with the naphthalene ring system and the benzene ring. The ester O-C=O plane and the benzene ring are almost coplanar, making a dihedral angle of 3.81?(18)°. The two meth-oxy groups lie essentially in the naphthalene ring plane [C-O-C-C torsion angles = 2.1?(2) and -1.44?(19)°]. In the crystal structure, a centrosymmetric dimer is formed through C-H?O bonds connecting the 7-meth-oxy group and the carbonyl O atom of the ester group. The dimers are further linked by C-H?O hydrogen bonds between the methoxy-carbonyl group and the bridging carbonyl O atom.

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

Project description: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.
