Bis(1-benzoyl-7-meth-oxy-naphthalen-2-yl) terephthalate.

ABSTRACT: The title molecule, C44H30O8, lies about a crystallographic inversion centre located at the centre of the central benzene ring. The benzene rings in the benzoyl and the terephthalate units make dihedral angles of 67.05?(7)° and 57.57?(7)°, respectively, with the naphthalene ring system. There is an intra-molecular C-H?O inter-action between the ketonic carbonyl O atom and an H atom on the naphthalene ring system. In the crystal, C-H?O inter-action of the benzene ring in the benzoyl group and weak C=O?? inter-action [O?centroid = 3.375?(2)?Å] of the naphthalene ring with the O atom in the ketonic carbonyl group are observed. These inter-actions form layers parallel to the bc plane.

(5-Benzoyl-3,6-dimeth-oxy-naphthalen-2-yl)(phen-yl)methanone.

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:In the title compound, C(25)H(16)Cl(2)O(4)·C(2)H(6)O, the two 4-chloro-benzoyl groups are in syn orientations with respect to the naphthalene ring system and are approximately parallel to each other: the dihedral angle between the benzene rings is 11.43 (16)°. The conformation around each of the carbonyl C-(C=O)-C groups forms a larger angle to the plane of the naphthalene ring system than that to the benzene ring; the angles of the C=O bond vector with the naphthalene ring system and the benzene ring are 55.4 (3) versus 13.5 (3)° and 52.2 (3) versus 17.9 (3)°. An intra-molecular O-H⋯O=C hydrogen bond generates a six-membered ring. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds including the ethanol solvent mol-ecule are observed. A C-H⋯O inter-action also occurs. The ethyl group of the ethanol mol-ecule is disordered over two positions with site occupancies of 0.63 and 0.37. The crystal studied was an inversion twin.
