摘　　要：以乙二肟和叠氮化钠(NaN3)为原料,采用一锅法制备了中间体二叠氮基乙二肟(DAG),然后DAG与HCl、Et2O反应合成5,5′-联四唑-1,1′-二羟基二水合物(BTO),BTO与氯化铵发生复分解反应合成了目标化合物5,5′-联四唑-1,1′-二氧氨盐(ABTOX),用X-射线单晶衍射仪对其晶体结构进行表征。采用DTA/TG技术研究了ABTOX的热行为,并测试了其感度。结果表明,该晶体属于正交晶系,空间群为Aba2(41)。晶体学参数为:a=1.07165(13)nm,b=1.070 33(13)nm,c=1.329 04(16)nm,V=1.524 4(3)nm3,z=4,D=1.779g/cm3。ABTOX的热分解温度为287.8℃,撞击感度(H50)为46cm,摩擦感度为0。The intermediate diazidoglyoxime （DAG）was synthesized by one-pot method with glyoxime and NaN3 as starting materials.Then 5,5′-bistetrazole-1,1′-diolate（BTO）was synthesized by reaction of DAG with HCl and Et2 O.The ammonia salt of 5 ,5′-bistetrazole-1 ,1′-diolate（ABTOX）was synthesized by metathesis reaction of BTO and NH4 Cl.Its structure was characterized by X-ray single crystal diffractometer.The thermolysis properties of ABTOX were studied by differential thermal analysis/thermogravimetric analysis （DTA/TG）,and its impact sensi-tivity and friction sensitivity were also tested.Results show that the crystal is orthorhombic belonging to space group of Aba2（41）with crystal parameters of the unit cell dimensions as follows：a= 1.071 65（13）nm,b= 1.070 33 （13）nm,c= 1.32904（16）nm,V= 1.5244（3）nm^3,z= 4,D= 1.779g/cm^3.The thermal decomposition temperature of ABTOX is 287.8℃ and its impact and friction sensitivities are 46cm and 0,respectively.
