High-nitrogen ID energetic complexes based on novel C-N linked 2,5-ditetrazolyl-1, 3,4-triazole (DTT)

摘要

Herein we synthesized two new one-dimensional high-nitrogen coordination compounds DTTK and DTTNa by using a new compound which is C-N linked 2, 5-ditetrazolyl-1, 3, 4-triazole (DTT) as a ligand. All new energetic compounds were fully characterized by IR and elemental analysis, and DTTK and DTTNa were further determined by single-crystal X-ray diffraction analysis. DTT is a new compound with a novel structure and high nitrogen content (76%) more than those of the commonly used high explosives. DTTK and DTTNa have high energetic positive heats of formation (DTTK: AfH°=6I4.8 /kJmol-1; DTTNa: ΔfH°=689.8 /kJ·mol-1) and good energetic properties. (DTTK: D = 7546 km s-1, P = 20.7 GPa; DTTNa: D = 7962 km s-l.P = 23.2 GPa).
