2-(2,7-Dimeth-oxy-1-naphtho-yl)benzoic acid.

ABSTRACT: In the title compound, C(20)H(16)O(5), the dihedral angle between the naphthalene ring system and the benzene ring is 67.43?(5)°. The bridging carbonyl C-C(=O)-C plane makes dihedral angles of 82.64?(6) and 41.79?(7)°, respectively, with the naphthalene ring system and the benzene ring. The dihedral angle between the carb-oxy O-C(=O)-C plane and the benzene ring is 36.38?(7)° and that between the bridging carbonyl C-C(=O)-C plane and the carb-oxy O-C(=O)-C plane is 51.88?(8)°. The crystal structure is stabilized by inter-molecular O-H?O and C-H?O hydrogen-bonding inter-actions. An intra-molecular C-H?O hydrogen bond occurs between a naphthalene H atom and the carbonyl O atom of the carb-oxy group.

Project description:In the title compound, C(21)H(18)O(5), the dihedral angle between the naphthalene ring system and the benzene ring is 86.65?(6)°. The bridging carbonyl C-C(=O)-C plane makes dihedral angles of 83.57?(7) and 20.21?(8)°, respectively, with the naphthalene ring system and the benzene ring.

The two meth-oxy groups lie essentially in the naphthalene ring plane [C-O-C-C torsion angles = 2.1?(2) and -1.44?(19)°]. In the crystal structure, a centrosymmetric dimer is formed through C-H?O bonds connecting the 7-meth-oxy group and the carbonyl O atom of the ester group. The dimers are further linked by C-H?O hydrogen bonds between the methoxy-carbonyl group and the bridging carbonyl O atom.

(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.

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)°.

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.

The nitro group is slightly out of the plane of the benzene ring [O-N-C-C torsion angle = 4.97?(17)°]. In the crystal, the packing is mainly stabilized by C-H?O inter-actions between an H atom of the benzene ring and an O atom of the nitro group.
