摘　　要：以五唑钴、甲脒盐酸盐和偶氮二甲脒盐酸盐为原料,合成了甲脒五唑盐(1)和偶氮胍基脲五唑盐(2)。采用X-射线单晶衍射(XRD)、傅里叶红外光谱(IR)、核磁共振(NMR)、差式扫描量热(DSC)和热重(TG)等对其进行了分析表征。结果表明:化合物1具有良好的平面性,其晶体具有层状的类石墨烯结构;化合物2阳离子的胍基与五唑阴离子具有平面性;化合物1和化合物2的初始分解温度分别为94.59℃和104.99℃;化合物1的爆速和爆压分别为8 399 m·s^(-1)和21.92 GPa;化合物2的爆速和爆压分别为8 212 m·s^(-1)和21.54GPa。化合物1和2的爆速爆压均高于TNT和AGN5。Formamidine pentazolate(1)and azoureidoguanidine pentazolate(2)were synthesized starting from cobalt pentazolate,formamidine hydrochloride,and azodimethamidine hydrochloride.Compounds 1 and 2 were characterized and analyzed by nuclear magnetic resonance(NMR),single crystal X-ray difraction(SC-XRD),fourier infrared spectroscopy(IR),differential scanning calorimetry(DSC)and thermogravimetry(TG).Data showed that compound 1 had a good planarity.The crystal of 1 had a layered graphene-like structure.The pentazolate anion and guanidyl of compound 2 had a good planarity.The initial decomposition temperatures of compounds 1 and 2 were 94.59℃and 104.99°℃,respectively.The detonation velocity and detonation pressure of compound 1 were8399m·s^(-1)and 21.92 GPa.The detonation velocity and detonation pressure of compound 2 were8212m·s^(-1)and 21.54 GPa.Generally,compounds 1 and 2 had a detonation velocity and a detonation pressure higher than those of TNT and AGNs.
