(4-Chloro-benzoyl)(2-eth-oxy-7-methoxy-naphthalen-1-yl)methanone.

ABSTRACT: In the title compound, C(20)H(17)ClO(3), the naphthalene and benzene rings form an inter-planar angle of 83.30?(8)°. The conformation around the central C=O group is such that the C=O bond vector forms a larger angle to the plane of the naphthalene ring than to the plane of the benzene ring, viz. 55.8?(2)° versus 15.8?(2)°. The 4-chloro-phenyl groups form a centrosymmetric ?-? inter-action, with a centroid-centroid distance of 3.829?(1)?Å and a lateral offset of 1.758?Å. An inter-molecular C-H?O inter-action is formed between the 4-chloro-phenyl group and the O atom of a neighbouring meth-oxy group, and two very weak C-H?? contacts are present.

Project description:The asymmetric unit of the title compound, C(26)H(20)O(4), contains two independent conformers. The aromatic rings of the aroyl groups are twisted with respect to the naphthalene ring systems to form dihedral angles of 66.58?(6) and 66.45?(6)° in one conformer, and 75.00?(7) and 81.17?(6)° in the other conformer. The crystal packing is stabilized by weak inter-molecular C-H?O hydrogen bonds and by C-H?? inter-actions.

(8-Benzoyl-2,7-dimeth-oxy-naphthalen-1-yl)(4-phen-oxy-phen-yl)methanone.

Project description:In the mol-ecule of the title compound, C32H24O5, the benzoyl group and the 4-phenoxy substituted benzoyl group at the 1- and 8-positions of the naphthalene ring system are aligned almost anti-parallel. The two benzene rings make a dihedral angle of 21.18?(10)°, and are inclined to the naphthalene ring system by 86.53?(9) and 82.95?(8)°, respectively. In the crystal, C-H?O inter-actions are observed involving aromatic and meth-oxy H atoms with ketonic carbonyl O atoms, as well as C-H?? inter-actions between aromatic H atoms and the ?-systems of naphthalene and benzene rings. These interactions form a three-dimensional architecture and afford a waved alignment of the naphthalene ring systems along the c axis.

Project description:The title mol-ecule, C30H28O6, possesses crystallographically imposed twofold symmetry, with two central C atoms in the naphthalene unit lying on the rotation axis along [001].
