In the title compound, C13H10N2O4, the nitro N atom deviates by 0.031 (2) Å from the plane of the benzene ring to which it is attached. The aromatic rings are oriented at a dihedral angle of 50.6 (1)°. An intra­molecular N—H...O hydrogen bond occurs. In the crystal, inversion dimers are formed by pairs of O—H...O inter­actions.

The complete mol­ecule of the title compound, C16H22N2O6, is generated by crystallographic inversion symmetry. The conformation of the N—C—O—C fragment of the side chain is approximately gauche [torsion angle = −74.84 (17)°]. In the crystal, weak C—H...O inter­actions link the mol­ecules.

The fluorene fragment of the title compound, C22H25N, is essentially planar, with an r.m.s deviation of the five-membered ring of 0.005 (2) Å. The dihedral angle between this ring and the outer benzene rings are 1.5 (2) and 0.7 (2)° while that between the benzene rings is 2.1 (2)°. The cyano group makes an angle of 0.3 (2)° with the attached benzene ring.
