摘要
One new organic adduct,isonicotinamide·3,5-dinitrosalicylic acid with isonico-tin-amide（ina） and 3,5-dinitrosalicylic acid（3,5-dnsa） in 1：1 molar ratio,has been synthesized.Its struc-ture（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 P1,with a = 8.812（4）,b = 9.487（5）,c = 9.604（6） ,α = 116.54（2）,β = 97.29（5）,γ = 98.35（4）°,V = 693.8（7） 3,Z = 2,Dc = 1.677 g/cm3,λ（MoKα） = 0.71073 ,μ = 0.142 mm-1,F（000） = 360,the final R = 0.0539 and 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.
