“…[23] It was found that 4,5-dinitroimidazole and 5-nitrotetrazole, which are strong NH acids (pK a = -0.8 for 5-nitrotetrazole) [24] with electron-withdrawing nitro substituents on the ring, can be readily quaternized with azoles to form energetic azolium-azolate salts.…”

“…In the vibrational spectra, there are significant shifts and broadening in the infrared spectral bands which are typically assigned to the NH 2 stretching environments. Typically upon N-protonation of one of the ring nitrogen atoms of a high nitrogen heterocycle with weakly basic pendant amino groups, there are blue shifts of the amino stretches typically in the range of 30 -50 cm À1 [13,17,41,55]. Accompanying this shift there is the appearance of a broad absorbance ranging from 2600 -2900 cm À1 that is strong evidence of À N À H À N hydrogen bonding resulting from interactions in the solid state.…”

“…Ein Nitrosubstituent verbessert die Sauerstoffbilanz energetischer Salze, sodass letztlich höhere Verbrennungswärmen erzielt und Detonationsvorgänge möglich werden. Die Sauerstoffkoeffizienten α 44 der Salze liegen zwischen 0.18 und 0.33 und somit im Bereich bekannter energetischer Verbindungen 45. Unter allen Azoliumazolaten hatte 1‐Methyl‐3‐azido‐1,2,4‐triazolium‐5‐nitrotetrazolat ( 43 d ) die höchste Bildungswärme.…”
