- Synthesis and Investigation of 2,3,5,6-Tetra-(1H-tetrazol-5-yl)pyrazine Based Energetic Materials
-
The structures and properties of several energetic compounds based on a high-nitrogen-content anion, namely 2,3,5,6-tetra(1H-tetrazol-5-yl)pyrazine (H4TTP) are reported here for the first time. These energetic salts were synthesized by reacting H4TTP with various alkali metal hydroxides (sodium, potassium, rubidium, caesium) and N-based (ammonia, hydrazine, hydroxylamine, guanidine carbonate, aminoguanidine bicarbonate). The resulting materials were comprehensively characterized by multinuclear (1H, 13C) NMR spectroscopy, infrared spectroscopy, elemental analysis, DSC, as well as low-temperature single-crystal X-ray diffraction. Heats of formation for the metal-free species as well as detonation parameters were calculated. The presented energetic materials (EMs) show high thermal stability (207 °C≤Tdec≤300 °C), while the metal-free ionic derivatives exhibit desirable properties such as detonation velocity (6873 m s?1≤VC-J≤8364 m s?1), detonation pressure (14.3 GPa≤pC-J≤24.9 GPa), and specific impulse (141.4≤Isp≤192.5 s).

- Synthesis and spectral properties of octacyanopyrazinoporphyrazine and its metallocomplexes
-
Octacyanopyrazinoporphyrazine was for first time synthesized by template tetramerization of tetracyanopyrazine, and its complexes with bivalent metals were prepared. The compounds obtained were characterized by MALDI-TOF mass spectral data, elemental anal
