One new organic adduct, isonicotinamide.3,5-dinitrosalicylic acid with isonico-tinamide(ina) and 3,5-dinitrosalicylic acid (3,5-dnsa) in 1:1 molar ratio, has been synthesized. Its structure (C13H10N4O8, Mr=350.25) was characterized by elemental analysis, IR and single-crystal X-ray diffraction analysis. The crystal belongs to the triclinic system, space group P(1), with a=8.812(4), b=9.487(5), c=9.604(6) (A), a=116.54(2),β=97.29(5), γ=98.35(4)°, V=693.8(7) (A)3,Z= 2, Dc=1.677 g/cm3, λ(MoKa)=0.71073 (A), μ=0.142 mm-1, F(000)=360, the final R=0.0539and wR=0.1402 for 2417 unique reflections(Rint=0.0288) with 1819 observed ones (I＞2σ(I)).Proton transfer reaction occurs between 3,5-dnsa and ina molecules, and the hydrogen bonds (N-H…O and C-H…O) with other interactions (π…π stacking and weak interactions of O…O and C…O) cooperatively construct a three-dimensional(3D) supramolecular structure.
