Abstract:
In the title compound, C36H28O4, the two 2-naphthoyl groups at the 1- and 8-positions of the central 2,7-dieth-oxy-naphthalene ring system are aligned almost anti-parallel and make a dihedral angle of 48.35 (5)°. The dihedral angles between the central 2,7-dieth-oxy-naphthalene ring system and the terminal naphthalene ring systems are 77.64 (4) and 73.73 (4)°. In the crystal, mol-ecules are linked into chains along the a-axis direction by dual C-H⋯O inter-actions between naphthoyl groups.

Structure and Nomenclature of Ethers
Ethers are organic compounds with an ether functional group which is characterized by an oxygen atom connected to two — identical or different — alkyl, aryl, or vinyl groups. The C–O–C linkage in dimethyl ether — the simplest ether — has an approximately tetrahedral bond angle of 110.3 degrees. The oxygen atom is sp3- hybridized, with the C–O distance being about 140 pm.

Structure and Nomenclature of Alcohols and Phenols
Alcohols are one of the most important functional groups in organic chemistry. The name of alcohol comes from the hydrocarbon from which it is derived. Alcohols are organic molecules containing the functional hydroxyl or –OH group directly bonded to carbon. Phenols have an OH group directly attached to a benzene ring. While alcohols are colorless, phenol is a white crystalline compound with a characteristic "hospital smell" odor.
As with other organic compounds, alcohols and phenols...
