A novel energetic coordination polymer [Pb(tza)2]n was synthesized by the reaction of PbCO3 and tetrazole-1-acetic acid in water solution, and characterized by elemental analysis and Fourier transform infrared (FT-IR) spectra. The crystal structure was investigated by using single-crystal X-ray diffraction, and it belongs to monoclinic system with space group C2/c, a＝1.5370(5) nm, b＝1.0373(3) nm, c＝0.8261(3) nm, β＝119.415(4)°, V＝1.1473(7) nm3, ρ＝2.671 g/cm3, Z＝2. The thermal decomposition process of [Pb(tza)2]n and non-isothermal kinetics analysis were investigated by using DSC and TG-DTG methods, also its sensitivities were tested according to the specifications. The study results verify that [Pb(tza)2]n presents good properties for potential application as an energetic material.
