1,2,3-Triazole and 1,2,4-triazole have been vigorously used in energetic materials research. Among these two, has a widely backbone designing new with improved performance. This study showed the synthesis of nitrogen-enriched dianionic salts (3–6) based on methylene bridged 3,4-diamino-1,2,4-triazole combined nitrate, perchlorate, picrate, azide anions. Structures 5,5′-methylenedi(4H-1,2,4-triazole-3,4-diamine) its 4 5 were confirmed by single-crystal X-ray diffraction studies, showing strong hydrogen-bonding network owing to presence –NH2 groups, numerous oxygen nitrogen atoms structure. The DSC results indicate acceptable thermal stabilities observed decomposition temperatures over 180 °C. All compounds are dense (1.70–1.86 g cm−3) exhibit reasonable detonation velocities (7.49–8.99 km s−1) pressures (21.9–28.2 GPa). Interestingly, salt 6 possess velocity comparable that RDX. These properties illustrate incorporating bridge ring can effectively support progress mechanically insensitive thermally stable future
