A new high nitrogen propellant compound, triaminoguanidinium azide nitrate TAZN, has been discovered. Single crystal x-ray diffraction data were obtained. The crystal and molecular structure of this orthorhombic Pbca compound was determined. Comparisons between the structures of TAGN and TAZN are discussed with emphasis upon possible hydrogen bonding. Triaminoguanidinium salts TAG apparently accelerate the burning rates of cyclic nitramine RDX, HMX based propellants, the nitrate TAGN with its relatively low flame temperature 2600 K has been used with RDX formulations not only to accelerate burning rates but to reduce flash and erosion. Over the years interest in triaminoguanidinium azide TAZ with its low flame temperature 2308 K has inspired propellant chemists to synthesize it.
