2,4,6,8 ‐ Tetranitro – 2,4,6,8 ‐ tetraazabicyclo[3.3.1]nonane‐3,7‐dione (TNPDU) has been synthesized from propane diurea by nitration with nitric acid‐acetic anhydride with a yield of 85 %. The molecular structure of the compound has been determined by elemental analysis, IR and 1 H‐NMR spectroscopy. Some of the properties including thermal and explosion delay behaviour of the compound and its mixtures with high explosives, are reported. An analogous compound 2,5,7,9‐tetranitro‐2,5,7,9‐tetraazabicyclo[4.3.0]nonane–8–one (TNABN) has also been evaluated for some of the explosive properties considering its good stability and insensitiveness as compared to other nitrodiurea derivatives.
