In the title compound, C32H30N2O7, the piperidone ring adopts a chair conformation and the five-membered ring of the dihydro­indenone ring system adopts an envelope conformation. Intra­molecular O—H...N and C—H...O hydrogen bonds occur. The dihedral angle between the two hydr­oxy-subsituted methoxy­phenyl rings is 71.12 (5)°. In the crystal structure, mol­ecules are connected by inter­molecular O—H...O hydrogen bonds, forming layers parallel to (001). These layers are further connected by C—H...O hydrogen bonds, forming a three-dimensional network.
