The mixture was heated at 40°-45° C. for five minutes and was then poured into ice. The solid was filtered off, washed with water and dried in a vacuum desiccator to give 0.109 g solid 3,3,7,7-Tetranitro-1,5-dinitrosoperhydro-1,5-diazocine. The solid was recrystallized from nitromethane to remove a small amount of starting material; mp: 190° C., onset of decomposition; 228°-229° C. melts; 1H NMR (acetone-d6): δ 4.81 (s), 5.26 (s), 5.73 (s), 6.16 (s).
