[2,7-Dimeth-oxy-8-(2-naphtho-yl)naphthalen-1-yl](naphthalen-2-yl)methanone.

ABSTRACT: The mol-ecule of the title compound, C(34)H(24)O(4), possesses crystallographically imposed twofold C(2) symmetry. The two 2-naphthoyl groups at the 1- and 8-positions of the central naphthalene ring are aligned almost anti-parallel [5.21?(5)°]. The dihedral angle between the central 2,7-dimeth-oxy-naphthalene unit and the terminal naphthyl groups is 75.13?(4)°. In the crystal, weak C-H?O hydrogen bonds and ?-? stacking inter-actions [centroid-centroid and inter-planar distances are 3.6486?(8) and 3.3734?(5)?Å, respectively] are observed.

(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-naphthalen-1-yl)(3-nitro-phen-yl)methanone.

Project description:The title compound, C(19)H(15)NO(5), has an intra-molecular C-H?O=C hydrogen bond between a naphthalene H atom and the O atom of the carbonyl group. The inter-planar angle between the naphthalene ring system and the benzene ring is 69.59?(5)°. The dihedral angle between the bridging carbonyl C-C(=O)-C plane and the naphthalene ring system is 61.02?(6)°, which is far larger than that between the bridging carbonyl plane and the benzene ring [12.68?(7)°]. 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.

(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.
