Abstract: The crystal structure of the title compound, C₁₈H₁₇N₃O₆, is formed by single molecules linked by N-HO hydrogen bonds into planar sheets. The dihedral angle between the mean planes of the pyridine and substituted phenyl rings is 84.2  (1)°. The 3-nitro substituent on the phenyl ring is rotated from coplanarity with the ring by only 3.7  (2)°.
