The new nitrogen-rich energetic compound 4-carboxamide-5-(1H-tetrazol-5-yl)-1H-1,2,3-triazole (2) and its sodium complex (3) have been synthesized using diaminomaleodinitrile as the starting material in a three step synthesis. Both of the compounds were comprehensively characterized using Fourier transform-infrared spectroscopy (FT-IR), mass spectrometry (MS) and elemental analysis (EA). The sodium complex of 4-carboxamide-5-(1H-tetrazol-5-yl)-1H-1,2,3-triazole was confirmed using single-crystal X-ray diffraction for the first time. The thermal stability of the two compounds has been measured using differential scanning calorimetry (DSC), which indicated that the decomposition peak temperatures were 332.6 °C (2) and 374.1 °C (3). The density and enthalpy of formation of 2 were calculated with Gaussian 09 and the detonation pressure (21.9 GPa) and the detonation velocity (7182 m s-1) were predicted by Kamlet-Jacobs equations. Compound 2 was not sensitive to impact (>40 J) or friction (>360 N).

Diazotization at 0 °C of N-[2-amino-1,2-dicyanovinyl]ethanamide 2a or propanamide 2b prepared from diaminomaleonitrile (DAMN) 1 using aqueous acetic acid and NaNO2 solution furnished sodium complex 3. The X-ray structure of the complex 3 showed that it is a 1:1 mixture of the neutral 2H-triazole heterocycle 4ii and its anion deprotonated at the central (N) atom of the ring, together with a sodium counter ion and two coordinated water molecules. However, when the diazotization reaction was carried out in the presence of aqueous HCl, the product was 5-cyano-2H-[1,2,3]triazole-4-carboxylic acid amide monohydrate 4ii. Diazotization of DAMN 1 using aqueous HCl furnished 1H-1,2,3-triazole-4,5-dicarbonitrile 5, whereas with acetic acid there was no reaction, and hence no route analogous to that leading to complex 3. The structure of both complex 3 and the triazole monohydrate 4ii were solved using X-ray crystallography, and the compounds under study were fully characterized using spectroscopic techniques.
