化合物5,5’-偶氮四唑钠(2)在稀盐酸中分解得到5-肼基四唑盐酸盐(3),5-肼基四唑盐酸盐与氢氧化钠中和后除去产物中的NaCl,在甲醇中重结晶得到5,5’-偶氮四唑-5-氮氧化物钠五水合物(4),采用MS,元素分析等对这些化合物进行表征.用X射线单晶衍射法测定获得了化合物3和4的晶体数据.化合物3属于单斜晶系,P2(1)/n空间群,其晶胞参数a=0.438(2)nm,b=2.395 6(2)nm,c=0.493 6(2)nm,Z=4,V=0.546(4)nm3,Dc=1.659g/cm3,F(000)=280;化合物4属于三单斜晶系,P-1空间群,其晶胞参数a=0.715 81(19)nm,b=0.766 3(2)nm,c=1.193 3(4)nm,Z=2,V=0.602 7(3)nm3,Dc=1.742g/cm3,F(000)=324.
5,5＇-azotetrazole（2） was dissolved in distilled water reacted with an excess of diluted hydrochloric acid to produce 5-hydrazinotetrazolium chloride （3）. 3 neutralized with sodium hydroxide to produce sodium 5,5＇-Azotetrazole-5-Oxide pentahydrate （4）. The structures of 3 and 4 were characterized by MS, 1H NMR and 13C NMR techniques, and the crystal structures of 3 and 4 were determined by X-ray single crystal diffraction analysis, 3 belongs to Monoclinic system with space group P2（1）/n and a=0. 438（2） nm, b=2. 395 6（2） nm, c=0. 493 6（2） nm, Z=4, V=0. 546（4） nm3 , Dc = 1. 659 g/cm3 ,F（000） =280; 4 belong to Triclinic system withspace groupP-1 and a=0.715 81（19） nm, b = 0. 766 3（2）nm,c=1.193 3（4） nm,Z=2,V= 0. 602 ？（3）nm3,Dc=1. 742 g/cm3,F（000）=324.
