The asymmetric unit of the title compound, C25H31NO4, contains two independent mol­ecules. In one mol­ecule, the benzene ring and an attached meth­oxy group were refined as disordered over two sets of sites in a 0.65 (4): 0.35 (4) ratio. In both mol­ecules, the central ring of the acridinedione system adopts a flattened boat conformation. The four essentially planar atoms of this ring [maximum deviations = 0.006 (5) Å in both mol­ecules] forms dihedral angles of 86.8 (2) and 87.6 (2)°, respectively, with the major and minor components in the disordered benzene ring and 87.3 (2)° with the benzene ring in the fully ordered mol­ecule. The two outer rings of the acridinedione system adopt sofa conformations in both mol­ecules. In the crystal, N—H...O hydrogen bonds form two independent chains along [100]. C—H...O hydrogen bonds link the chains, forming a three-dimensional network.

In the title mol­ecule, C19H17F3N2O2, the fused cyclo­hexene and pyran rings adopt sofa and flattened boat conformations, respectively. The four essentially planar atoms of the pyran ring [maximum deviation = 0.008 (2) Å] form a dihedral angle of 88.13 (9)° with the benzene ring. The F atoms of the trifluoro­methyl group were refined as disordered over three sets of sites in a 0.507 (7):0.330 (7):0.163 (3) ratio. In the crystal, mol­ecules are connected into inversion dimers via pairs of N—H...N hydrogen bonds and these dimers are further linked by N—H...O hydrogen bonds into a two-dimensional network parallel to (100).
