(3-Ethyl-6,7-dimeth-oxy-naphthalen-1-yl)(phen-yl)methanone.

ABSTRACT: The asymetric unit of the title mol-ecule, C(21)H(20)O(3), contains two crystallographically independent mol-ecules, A and B, which differ in the orientation of the ethyl group substituted on the naphthalene system; the dihedral angles between the ethyl group and the naphthalene system are 7.4?(3) and 68.1?(3)°, respectively, for mol-ecules A and B. The dihedral angles between the benzoyl and naphthalene groups are 64.7?(7) and 69.4?(8)°, respectively, for mol-ecules A and B. The crystal structure features four aromatic ?-? stacking interactions [centroid-centroid distances = 4.181?(1), 3.891?(1), 4.423?(1) and 4.249?(1)?Å].

(3,6-Dimeth-oxy-naphthalen-2-yl)(phen-yl)methanone.

Project description:In the title compound, C(19)H(16)O(3), the dihedral angle between the naphthalene ring system and the phenyl ring is 68.32 (5)°. The bridging carbonyl C-C(=O)-C plane makes a dihedral angle of 54.32 (5)° with the naphthalene ring system and 21.45 (6)° with the phenyl ring. An inter-molecular C-H⋯O hydrogen bond exists between the H atom of one meth-oxy group and the O atom of the second meth-oxy group in an adjacent mol-ecule. The crystal packing is additionally stabilized by a weak C-H⋯O inter-molecular inter-action between an H atom of the naphthalene ring and the O atom of the carbonyl group.

(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.

Project description:In the title mol-ecule, C25H20O4, the naphthalene and phen-oxy groups are oriented nearly perpendicular with respect to the benzene ring of the benzoyl group, with dihedral angles of 89.61?(5) and 86.13?(6)°, respectively. The crystal structure features C-H?O and 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.

(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.
