(4-Ethoxybenzoyl)[8-(4-ethoxybenzoyl)-2,7-dimethoxynaphthalen-1-yl]methanone
The title molecule, C(30)H(28)O(6), possesses crystallographically imposed twofold symmetry, with two central C atoms in the naphthalene unit lying on the rotation axis along [001]. The 4-ethoxybenzoyl groups at the peri positions of the naphthalene ring system are disordered over two sets of sit...

description | The title molecule, C(30)H(28)O(6), possesses crystallographically imposed twofold symmetry, with two central C atoms in the naphthalene unit lying on the rotation axis along [001]. The 4-ethoxybenzoyl groups at the peri positions of the naphthalene ring system are disordered over two sets of sites with occupancies of 0.769 (4) and 0.231 (4). They are directed in opposite directions from the naphthalene plane (anti orientation). For the major component, the dihedral angle between the aroyl benzene ring and the naphthalene ring system is 75.62 (13)° [minor component 75.5 (4)°], and that between the aroyl benzene rings is 32.58 (15)°. In the crystal, molecules are linked via C—H⋯O and C—H⋯π interactions, forming a three-dimensional network. |
