A new energetic material dirubidium 5,5＇-bis （ tetrazole-1 -oxide） （BTORb） was synthesized by using I H, 1 ＇ H-5,5 ＇- bistetrazole-1 ,1 ＇-diolate （BTO） as the original material. The monocrystal of target salt was first cultivated by the method of gradu- al evaporation, and the single crystal structure was menstruated by single X-ray diffraction. It is found that the Rb＋ and BTO2- formed a dissymmetrical structure. In different layers, they are alternately arranged and connected with each other, forming a three-dimensional reticular structure. Its thermal decomposition behavior was investigated through DSC and TG-DTG technologies, indicating a good thermal stability with a decomposition temperature beginning at 292℃. Its kinetic parameters of non-isothermal reaction was calculated by Kissinger and Ozawa methods with the equation of Arrhenius is Ink–13.51 -1 86.3×10^3/RT. Its standard heat of formation was calculated with the result of 274.91 kJ·mol^-1. Its critical temperature of thermal explosion Tb is 356.7℃, indicating that the salt has a good thermal stability. The impact sensitivity （H50） of BTORb is 34.8 cm, with the drop hammer of 800 g. The friction sensitivity is 36%, under the condition of 70°, 1. 23 MPa. The 50% fire energy of electrostatic spark sensitivity is 0.34 J.
