“…In general, all bond lengths and angles were observed as expected and are comparable to similar crystal structures of furazanes, [9] furoxanes, [10] and tetrazole-oxides [11] in literature. Compound 3 crystallizes in the monoclinic space group C2/c with four molecules in the unit cell.…”

ARTICLE This journal isThe connection of highly endothermic heterocycles with high nitrogen but also oxygen content is a recent trend in the development of new energetic materials in order to increase densities and stabilities. Bis(1-hydroxytetrazolyl)furazane (9) and bis(1-hydroxytetrazolyl)furoxane (10) were synthesized for the first time from dicyanofurazane and dicyanofuroxane, respectively. Several nitrogen-rich (e.g. ammonium and hydroxylammonium) and metal salts thereof were prepared. Most compounds were characterized by single crystal X-ray diffraction. In addition all compounds were analyzed by vibrational spectroscopy (IR and Raman), multinuclear NMR spectroscopy, elemental analysis and DSC measurements. The heats of formation of 4, 5, 15-16, 20 and 24 were calculated using the atomization method based on CBS-4M enthalpies. With these values and the experimental (X-ray) densities several detonation parameters such as the detonation pressure, velocity, energy and temperature were computed using the EXPLO5 code (V.5.05). In addition, the sensitivities towards impact, friction and electrical discharge were tested using the BAM drop hammer and friction tester as well as a small scale electrical discharge device.

“…7 In the aspect of energetic salts, as shown in Scheme 1, anions containing the furoxan ring and other energetic groups or backbones bearing acidic protons, have been investigated. [8][9][10][11] In 2012, Z. Zhou et al synthesized a series of energetic monoanionic and dianionic salts of 3,4-bis(1H-tetrazol-5-yl)furoxan with good thermal stabilities and rather high densities. 8,9 In the next year, nine energetic salts based on 4-nitro-3-(5-tetrazolate)furoxan anion were also synthesized and fully characterized by them.…”

A new family of energetic salts based on a new guanidinium cation containing furoxanyl functionality, 1-(3'-methylfuroxanyl)methyleneamino guanidinium cation, were synthesized and well characterized by IR and multinuclear NMR spectroscopy, elemental analys is as well as differential scanning calorimetry. The structures of salts 1, 4, 5 and 6 were confirmed by single-crystal X-ray diffraction. Most of the salts decompose at temperatures over 180 o C. Furthermore, except for salts 7 and 9, the remaining energetic salts exhibit low impact sensitivities (15-40 J), friction sensitivities (120-360 N), and are insensitive to electrostatics. The detonation pressure values calculated for these salts range from 19.3 to 27.5 GPa, and the detonation velocities range from 7515 to 8402 m s -1 . These results make some energetic salts potential candidates for energetic materials with good thermal stabilities and low sensitivities.
