2,7-Dimethoxy--1-(4-nitro-benzo-yl)-naphthalene.

ABSTRACT: In the title compound, C(19)H(15)NO(5), the dihedral angle between the naphthalene ring system and the benzene ring is 61.97 (5)°. The dihedral between the naphthalene ring system and the bridging carbonyl C-C(=O)-C plane is 54.68 (6)°, far larger than that [12.54 (7)°] between the phenyl group and the bridging carbonyl group. The nitro group and the phenyl ring are almost coplanar [O-N-C-C torsion angle = 2.94 (19)°]. In the crystal, mol-ecules are linked by C-H⋯π inter-actions and the phenyl rings are involved in a centrosymmetric π-π inter-action with a perpendicular distance of 3.523 Å and a lateral offset of 1.497 Å. In addition, weak inter-molecular C-H⋯O hydrogen bonds are formed between an H atom of one meth-oxy group and a nearby carbonyl O atom.

Project description:The title compound, C(26)H(18)F(2)O(4), is a naphthalene derivative in which the two aroyl groups at the 1- and 8-positions (peri positions) are anti to each other.

Project description:The title compound, C28H22N2O8, possesses crystallographically imposed twofold symmetry, with the two central carbon atoms of the naphthalene unit lying on the rotation axis. The two benzoyl groups in the mol-ecule are twisted away from the attached naphthalene unit with a C-C-C=O torsion angle of 49.05 (15)° between the naphthalene unit and the carbonyl group.

Project description:The asymmetric unit of the compound, C19H15FO3, contains two independent molecules.
