1,4-Bis(4-methoxyphenyl)naphthalene

The title naphthalene derivative, C24H20O2, features 4-methyoxy-substituted benzene rings in the 1 and 4 positions of the naphthalene ring system. There are two crystallographically independent molecules (A and B) in asymmetric unit. The independent molecules have very similar conformations in which the naphthalene ring systems are only slightly bent, exhibiting dihedral angles between the constituent benzene rings of 3.76 (15) and 3.39 (15)° for A and B, respectively. The pendent 4-methyoxybenzene rings are splayed out of the plane through the naphthalene ring system to which they are connected [range of dihedral angles = 59.63 (13) to 67.09 (13)°]. In the crystal, the molecular packing is consolidated by intermolecular C—H...π interactions, leading to supramolecular chains along the b axis. The chains assemble without directional interactions between them.
