| Abstract: | The title compound C2N5H6+C6N3O7H2-was synthesized by the reaction of 3,5diamino-1,2,4-triazole and picric acid in the mixture of ethanol and water solution.Single crystals suitable for X-ray measurement were obtained at room temperature.The structure was characterized by elemental analysis and IR and determined by X-ray diffraction analysis.Crystallographic data：C8N8H8O7,Mr = 328.22,monoclinic,space group C2/c with a = 22.815(2),b = 4.8086(5),c =22.564(2)(A),β = 93.976(2)°,V= 2469.6(4)(A)3,Dc = 1.766 g/cm3,Z = 8,μ = 0.156 mm-1,F(000)=1344,the final R= 0.0309,wR= 0.0864. |
