An Energetic (Nitro‐<i>NNO</i>‐azoxy)triazolo‐1,2,4‐triazine

Abstract

7‐Nitro‐3‐(nitro‐ NNO ‐azoxy)[1,2,4]triazolo[5,1‐ c ][1,2,4]‐triazin‐4‐amine ( 4 ) is the first high‐melting compound bearing adjacent nitro‐ NNO ‐azoxy and amino groups. It was synthesized by nitration of 7‐nitro‐3‐( tert ‐butyl‐ NNO ‐azoxy)[1,2,4]triazolo[5,1‐ c ][1,2,4]triazin‐4‐amine ( 3 ) with NO 2 BF 4 . Compound 4 is a rather thermally stable (decomposition onset temperature 154 °C), highly energetic (calculated heat of formation 580 kcal · kg –1 ), and highly dense (1.875 g cm –3 ) material with a CO‐level oxygen balance.
