(2,7-Di-meth-oxy-naphthalen-1-yl)(naph-thalen-1-yl)methanone.

ABSTRACT: The asymmetric unit of the title compound, C23H18O3, contains two independent mol-ecules (A and B). Each mol-ecule has essentially the same conformation (r.m.s. deviation of fitted mol-ecules = 0.173?Å) with the aromatic rings twisted in a near perpendicular manner. The dihedral angles between the two naphthalene ring systems are 79.07?(4) and 88.19?(4)° in the two independent mol-ecules. In the crystal, the A mol-ecules are connected by C-H?O inter-actions, forming chains along the b-axis direction. Further C-H?O inter-actions between the H atoms of the meth-oxy group and the O atoms of the carbonyl units link the A and B mol-ecules, forming a three-dimensional network.

(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:The title mol-ecule, C30H28O6, possesses crystallographically imposed twofold symmetry, with two central C atoms in the naphthalene unit lying on the rotation axis along [001].
