In the title compound, C23H20N2O3·CH3OH, the hexa­hydro-1H-benzo[f]isoindole and indoline rings are planar, with maximum deviations of 0.092 (1) and −0.095 (1) Å, respectively. The dihedral angle between these two rings is 88.03 (4)°. An O—H...N inter­action links the main mol­ecule and the methanol solvent mol­ecule. An intra­molecular C—H...O inter­action forms an S(6) ring motif. In the crystal, the mol­ecules form two-dimensional layers parallel to the bc plane through N—H...O and C—H...O inter­actions.

In the title compound, C26H18N2O3, the maximum deviations from planarity for the tetra­hydro-1H-naphtho­[2,3-c]pyrrole and indoline rings systems are 0.091 (1) and 0.012 (2) Å, respectively. These ring systems make a dihedral angle of 89.95 (6)° with each other and they make dihedral angles of 73.42 (8) and 71.28 (9)°, respectively, with the benzene ring. In the crystal, inversion dimers linked by pairs of N—H...O hydrogen bonds generate R22(8) loops and C—H...O inter­actions connect the dimers into corrugated sheets lying parallel to the bc plane.
