Numerous nitramine bridged compounds which show promising combinations of properties have already been identified in the area energetic materials. In this work, four new nitrazapropane tetrazoles, as well trinitrazaheptane tetrazoles and three oxapropane were synthesized fully characterized. These can all be by a simple, one-step synthesis using Finkelstein conditions. All these materials characterized NMR spectroscopy, single crystal X-ray diffraction, vibrational analysis elemental analysis. The thermal behaviour was studied differential (DTA) partly thermogravimetric (TGA). BAM standard method used to determine sensitivities towards impact (IS) friction (FS). enthalpies formation calculated at CBS-4M level, performances EXPLO5 (V6.06.01) computer code. compared each other known material RDX.

5-aminotetrazole is one of the most marked high-nitrogen tetrazole compounds. However, structural modification with nitro groups often leads to dramatically decreased molecular stability, while N-bridging functionalization does not efficiently improve density and performance. In this paper, we report on a straightforward approach for improving by introducing 4-amino-3,5-dinitropyrazole. The following experimental calculated properties show that nitropyrazole competes well energetic performance mechanic sensitivity. All compounds were thoroughly characterized using IR NMR spectroscopy, elemental analysis, differential scanning calorimetry (DSC). Two (
