The mol-ecules in the crystal structure of the title compound, C(20)H(15)NO(2), form inversion dimers connected through the C-H⋯N and π-π inter-actions. These dimers are further linked by C-H⋯π inter-actions. The meth-oxy group is nearly coplanar with the acridine ring system [dihedral angle = 4.5 (1)°], whereas the phen-oxy fragment is nearly perpendicular to it [dihedral angle = 85.0 (1)°]. The mean planes of the acridine ring systems are either parallel or inclined at angles of 14.3 (1), 65.4 (1) and 67.3 (1)° in the crystal.
