(2,7-Dimethoxy-naphthalene-1,8-di-yl)bis-(4-fluoro-benzo-yl)dimethanone.

ABSTRACT: 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. There is an appreciable difference in the dihedral angles between the naphthalene ring system and the two benzene rings [66.88?(7)° and 88.09?(6)°]. In the crystal, weak C-H?O inter-actions involving one of the carbonyl groups and an aromatic C-H group ortho to the F atom seem to stabilize the packing of the mol-ecules.

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. There is an appreciable difference in the dihedral angles between the naphthalene ring system and the two benzene rings [66.88 (7)° and 88.09 (6)°].

1,8-Bis(4-amino-benzo-yl)-2,7-dimeth-oxy-naphthalene.

Project description:The title compound {systematic name: [8-(4-aminobenzoyl)-2,7-dimethoxynaphthalen-1-yl](4-aminophenyl)methanone}, C(26)H(22)O(4)N(2), possesses crystallographically imposed twofold symmetry, with two C atoms lying on the rotation axis.

Furthermore, weak C-H?O hydrogen bonds and ?-? stacking inter-actions between the benzene rings are observed. The centroid-centroid and inter-planar distances between the benzene rings of the aroyl group and the naphthalene ring systems of adjacent mol-ecules are 3.6954?(8) and 3.2375?(5)?Å, respectively. The dihedral angle between the mean planes of the benzene ring and the naphthalene ring system is 83.59?(5)°. The benzene ring and the carbonyl group in the benzoyl unit are almost coplanar [C-C-C-O torsion angle = 175.91?(10)°].

2,7-Dimeth-oxy-1,8-bis-(4-phen-oxy-benzo-yl)naphthalene.

Project description:In the title mol-ecule {systematic name: [2,7-dimethoxy-8-(4-phenoxybenzoyl)naphthalen-1-yl](4-phenoxyphenyl)methan-one}, C(38)H(28)O(6), the 4-phen-oxy-benzoyl units adopt a syn orientation with respect to the naphthalene ring system. The inter-nal benzene rings, A and B, make dihedral angles of 86.72?(5) and 79.22?(5)° with the naphthalene ring system. The two terminal benzene rings, C and D, of the 4-phen-oxy-benzoyl groups are twisted with respect to benzene rings A and B, with dihedral angles of A/C = 62.72?(8) and B/D = 87.61?(6)°. In the crystal, H atoms in the naphthalene system make two types of inter-molecular C-H?O inter-actions with the carbonyl O atom and the phenyl etheral O atom of neighbouring mol-ecules. Mol-ecules are further linked by C-H?? inter-actions involving a H atom of terminal benzene ring D and the ?-system of the inter-nal benzene ring A, forming dimers centered about an inversion center.

1,8-Dibenzoyl-2,7-dimethoxy-naphthalene.

Project description:The mol-ecule of the title compound, C(26)H(20)O(4), is located on a twofold rotation axis. The two benzoyl groups are situated in an anti orientation. The dihedral angle between the mean planes of the phenyl ring and the naphthalene ring system is 80.25 (6)°. The phenyl and carbonyl groups in each benzoyl group are almost coplanar.
