Abstract: In the title compound, C₁₉H₁₅NO₄, the acridine system is essentially planar (r.m.s. deviation = 0.015 Å). The crystal packing exhibits [pi] - [pi] interactions between pairs of centrosymmetric molecules, one of them between the central heterocyclic rings and others between the outer benzene rings of the acridine systems, with centroid-centroid distances of 3.692 (1) and 3.754 (1) Å, respectively. These pairs are further linked by additional [pi] - [pi] interactions along the a-axis direction through one of the two outer benzene ring of neighboring molecules, with a centroid-centroid distance of 3.642 (2) Å.
