Tetrazole-acetic acid was reacted with lead carbonate to prepare a coordination polymer [Pb (tza) 2] n (Htza = tetrazole-1 H-1-acetic acid) The results show that the crystal belongs to the monoclinic space group C2 / c, a = 1.5370 (5) nm, b = 1.0373 (3) nm and c = 0.8261 (3) nm, β = 119.415 (4) °, V = 1.1473 (7) nm3, ρ = 2.671 g / cm3, and Z = 2.Using differential scanning calorimetry (DSC) and TG- (TG-DTG) to study the thermal decomposition process of the complex and its non-isothermal reaction kinetics, and the sensitivity of the complex was tested according to the relevant standards.The results show that the complex has good thermal stability and Appropriate sensitivity, decomposition reaction release a lot of heat and gas products, is expected to be used as energy-containing materials in related fields.
