The title naphthalene derivative, C24H20O2, features 4-methy-oxy-substituted benzene rings in the 1 and 4 positions of the naphthalene ring system. There are two crystallographically independent mol-ecules (A and B) in asymmetric unit. The independent mol-ecules 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 mol-ecular packing is consolidated by inter-molecular C-H⋯π inter-actions, leading to supra-molecular chains along the b axis. The chains assemble without directional inter-actions between them.
Keywords: C—H⋯π interactions; crystal structure; naphthalene derivative.
