Abstract A new nitrogen-rich energetic complex Cd(DMF)2BTZAF (1) (DMF= N,N-Dimethylformamide, H2BTZAF= 3, 3′-bis(1H-tetrazol-5-yl)-4, 4′-azofurazan) was first synthesized by the reaction of Cd(NO3)2·4H2O with 4-amino-3-(5-tetrazolate)-furazan. The compound 1 was characterized by elemental analysis and FT-IR spectrum analysis, respectively. The crystal structure of complex 1 was determined by single-crystal X-ray diffraction. It revealed that 1 crystallizes in the monoclinic space group P21/c. A Cd2+ ion is coordinated by four N atoms and two O atoms to form a distorted octahedral structure. Among them, four nitrogen atoms are from the four BTZAF2− ions and the other two oxygen atoms are from two DMF molecules. Moreover, the thermal decomposition behavior of compound 1 was studied with DSC and TG-DTG methods. The non-isothermal kinetic parameters of compound 1 was calculated by Kissinger's method and Ozawa-Doyle's method. In addition, the thermal safety performance and the impact sensitivity of complex 1 were measured and calculated, and the results showed that the synthetic compound has good insensitivity and stability.
