The title compound, a 1:1 molecular adduct of 3-nitrophthalic acid and 3-methyl- 4-nitropyridine N-oxide (PPOM), has been synthesized and characterized by X-ray single-crystal structure analysis. It crystallizes in triclinic, space group P1 with a = 7.6076(15), b = 7.8180(16), c = 14.546(3) ?, α = 93.90(3), β = 97.21(3), γ = 114.43(3)o, C14H11N3O9, Mr = 365.26, Z = 2, V = 774.6(3) ?3, Dc = 1.566 g/m3, μ(MoKα) = 0.134 mm?1, F(000) = 376, R = 0.0538 and wR = 0.1460 for 885 observed reflections (I > 2σ(I)). The protons of the carbonylic acids in the molecule are not transferred and the O–H…O and C–H…O hydrogen bonds form zigzag chains in the molecule.
