The synthesis and characterization of the metal‐free polyazido compounds 3,6‐bis‐(2‐(4,6‐diazido‐1,3,5‐triazin‐2‐yl)‐hydrazinyl)‐1,2,4,5‐tetrazine (2) and 3,6‐bis‐(2‐(4,6‐diazido‐1,3,5‐triazin‐2‐yl)‐diazenyl)‐1,2,4,5‐tetrazine (4) are presented. Two compounds were characterized by NMR spectra, IR spectroscopy, mass spectrometry, and differential scanning calorimetry (DSC). Additionally, the structure of 2was confirmed by single‐crystal X‐ray diffraction. Compounds 2 and 4exhibit measured densities (1.755 g cm−3 and 1.763 g cm−3), good thermal stabilities (194 °C and 189 °C), high heat of formation (2114 kJ mol−1 and 2820 kJ mol−1), and excellent detonation performance (D, 8365 m s−1 and 8602 m s−1; P, 26.8 GPa and 29.4 GPa). Furthermore, compounds 2 and 4have been tested for their priming ability to detonate RDX. The results indicate that the title compound 2 is a potential environmentally friendly alternative candidate to lead‐based primary explosives.
