9-(4-Methoxyphenyl)anthracene

In the title compound, C21H16O, the dihedral angle between the anthracene ring system and the benzene ring is 74.3 (5)°. The anthracene ring system is essentially planar (r.m.s. deviation = 0.0257 Å) and the methoxy group lies in the plane of the benzene ring [C1—O1—C2—C7 torsion angle = 0.5 (2)°]. The crystal structure features π–π [centroid–centroid distance = 3.9487 (12) Å] and C–H...π interactions, forming a sheet running along the a-axis direction.
