ABSTRACT: In the mol-ecule of the title compound, CHO, 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⋯π inter-actions between aromatic H atoms and the π-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 axis.

ABSTRACT: The title compound, CHO, crystallized with two independent molecules in the asymmetric unit. Each molecule has essentially the same feature of non-coplanar aromatic rings whereby the two 4-isopropoxybenzoyl groups are twisted in a perpendicular manner to the naphthalene ring and oriented in the same direction (-orientation). The benzene rings of the aroyl groups make dihedral angles of 16.13 (7) and 25.31 (7)° in the two molecules. These benzene rings make dihedral angles of 88.38 (8) and 75.32 (7)° with the naphthalene ring system in one molecule, and 89.71 (7) and 82.11 (7)° in the other. In the crystal, mol-ecules are linked C-H⋯O hydrogen bonds, forming a three-dimensional network. In one independent molecule, the 2-propyl groups of both isoprop-oxy groups are disordered over two positions with site occupancies of 0.512 (3) and 0.488 (3).

The dihedral angle between the best planes of the benzene rings of the benzoyl moieties and the naphthalene ring system is 70.52 (5)° and that between the best planes of the benzene rings of the phen-oxy groups and the naphthalene ring system is 27.80 (6)°. In the crystal, mol-ecules are linked into a three-dimensional architecture by C-H⋯O and C-H⋯π inter-actions.

ABSTRACT: In the title compound, C(36)H(24)O(6), the benzoyl groups at the 1- and 8-positions of the naphthalene system are in an anti orientation. Both carbonyl groups form intra-molecular O-H⋯O hydrogen bonds with hy-droxy groups affording six-membered rings. The benzene rings of the benzoyl groups make dihedral angles of 59.26 (13) and 59.09 (13)° with the naphthalene ring system. Zigzag C-H⋯O chains and ladder C-H⋯O chains between the phenoxybenzoyl groups along the ab diagonals form an undulating checkered sheet. The molecules are further connected into a three-dimensional network by C-H⋯π interactions.
