Keeping the Same Ratio of the Ligand and Perchlorate: Realizing the High Performance of Energetic Materials by Changing the Bonding Mode

The Journal of Physical Chemistry C, Год журнала: 2023, Номер 127(27), С. 12923 - 12930

Опубликована: Июнь 27, 2023

In addition to the three classical methods for adjusting performance of energetic complexes, in order explore influence different bonding types on materials, we designed ionic salts PZCA·HClO4 (3) and ECPs [Ag(PZCA)ClO4]n (4) with PZCA(1H-pyrazole-4-carbohydrazide) as ligand. They use same ligands oxidizing acids also have N/O number. On basis their structures compositions confirmed by infrared spectroscopy, elemental analysis, single-crystal X-ray diffraction, characterization physical chemical properties shows that 4 has better thermal decomposition behavior (ΔT = 30 °C), more suitable mechanical sensitivity (IS 5 J, FS 9 N), outstanding initiation performance. After studying mechanism, find bonds (H bond or coordination covalent bond) lead mechanisms (redox reaction free radical reaction) and, finally, show great differences explosive properties.

Tailoring Transition Metals and Biuret into Laser-Ignitable Energetic Coordination Polymers with Improved Oxygen Balance and Multidentate Coordination Structures

Crystal Growth & Design, Год журнала: 2023, Номер 23(3), С. 1959 - 1971

Опубликована: Фев. 1, 2023

Eight kinds of energetic coordination polymers (ECPs) with multi-coordination were designed and synthesized by combining the carbonyl group potential in biuret transition metal nitrates perchlorates (Co2+, Ni2+, Cu2+, Ag+). The structures these complexes are confirmed infrared spectroscopy, elemental analysis, X-ray single-crystal diffraction. physical chemical performance test results show that solvent-free ECPs 7 (Cu(BIU)2(ClO4)2) has best (Tdec = 328 °C, D 7600 km·s–1, P 27.8 Gpa, IS 25 J, FS 240 N). Among them, 8 (Ag(BIU)ClO4) have good detonation during hot plate laser ignition tests (ECPs 7: 15 W, τ 6 ms, E 80 mJ; 8: 20 5 100 mJ). result shows improving oxygen balance ligands constructing multidentate may be a new effective strategy for laser-sensitive ECPs.
