[8-(4-Chloro-benzo-yl)-2,7-dimeth-oxy-naphthalen-1-yl](2,4,6-trimethyl-phen-yl)methanone.

ABSTRACT: In the title compound, C(29)H(25)ClO(4), the dihedral angle between the benzene rings of the 2,4,6-trimethyl-benzoyl group and the 4-chloro-benzoyl group is 65.19 (9)°. The dihedral angles between the naphthalene ring system and the benzene rings of the 2,4,6-trimethyl-benzoyl group and the 4-chloro-benzoyl group are 85.66 (8) and 69.48 (8)°, respectively. In the crystal, two types of inter-molecular C-H⋯O inter-actions and an intra-molecular C-H⋯O inter-action are observed. Moreover, there is a short intra-molecular C=O⋯C=O contact of 2.614 (2) Å between the benzoyl substituents.

[2,7-Dimeth-oxy-8-(4-meth-oxy-benzo-yl)naphthalen-1-yl](4-meth-oxy-phen-yl)methanone chloro-form monosolvate.

Project description:In the title compound, C28H24O6·CHCl3, the two 4-meth-oxy-benzoyl groups at the 1- and 8-positions of the naphthalene ring system are aligned almost anti-parallel, the benzene rings making a dihedral angle of 25.76?(7)°.

(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.
