The synthesis of a series of nitroxy- and azido-functionalized compounds, based on 4-amino-3,5-di(hydroxymethyl)-1,2,4-triazole, for possible use as an energetic plasticizers is described. All compounds were fully characterized. Two of them were further confirmed by X-ray single crystal diffraction. Energetic performance was calculated by using EXPLO5 v6.01 based on calculated heats of formation (Gaussian 03) and experimentally determined densities at 25 °C. The results show that the nitration product 1-nitro-3,5-di(nitroxymethyl)-1,2,4-triazole, containing a nitro group and two nitroxy groups, exhibits good detonation properties (D=8574 m s(-1) , P=32.7 GPa). In addition, its low melting point makes it very attractive as an energetic plasticizer in solid propellants.
