Abstract
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.
