2-Methylphenyl 2-methoxyacridine-9-carboxylate

The title compound, C(22)H(17)NO(3), crystallizes in the monoclinic space group P2(1)/c with four molecules per unit cell. The molecules are arranged in centrosymmetric pairs, joined via the C and attached H atoms in the meta position relative to the methoxy group. These pairs are bonded in the crystalline phase as a result of non-specific dispersive interactions, and through a network of C-H...O interactions involving the non-bonded O atom of the carboxy group and, to some extent, the O atom of the methoxy group. The methoxy substituent lies in the plane of the almost planar acridine moiety and is directed towards the phenyl ester group. The phenyl ester group itself is twisted by 35.9 (5) degrees relative to the mean plane of the acridine moiety.
