摘　　要：制备了四水合5,5′-联四唑-1,1′-二氧锂盐[Li2(BTO)(H2O)4]n,培养了[Li2(BTO)(H2O)4]n的单晶。采用X-射线衍射仪测定了单晶结构。采用DTA/TG技术研究了[Li2(BTO)(H2O)4]n的热性能,并测试了其撞击感度和摩擦感度。结果表明,该晶体属于三斜晶系,空间群为P-1,晶体学参数为:a=0.534 5(17)nm,b=0.636 3(2)nm,c=0.830(3)nm,α=105.904(7),β=98.216(7),γ=111.516(7),V=2.430 2(13)nm3,z=2,D=1.736g/cm3。其热分解峰温为349.1℃,撞击感度为71.8cm,摩擦感度为0。Dilithium 5 ,5’-bistetrazole -1 ,l ’-diolate tetrahydrate[Li2 （ BTO） （ H2 0 ） 4 ] n was prepared and its singlecrystal was cultured. The single crystal structure was determined by a X-ray single crystal diffractometer. The thermalperformance of [L i2 （BTO） （ H20）4 ] n was studied by differential thermal analysis/thermogravimetry （DTA/TG） technique, and its impact sensitivity and friction sensitivity were measured. The results show that the crystal istriclinic belonging to space group P-1 with crystaphicllogra parameters of α = 0. 5345（17） nm,6= 0. 636 3 （2） nm,c= 0. 830（3） nm,a = 105. 9 0 4 （7 ）,β=98. 2 1 6 （7 ）,y = l l l . 5 1 6 （7 ）,V=2. 4302 （13） nm3, z = 2 ,D = 1. 736 g/cm3.Its thermal decomposition peak temperature is 349. 1°C , the impact sensitivity and friction sensitivity are 71. 8 cmand 0 ,respectively.
