Silver Salt of 4,6-Diazido-N-nitro-1,3,5-triazine-2-amine Characterization of this Primary Explosive

A new primary explosive, the silver salt of 4,6-diazido-N-nitro-1,3,5-triazine-2-amine (AgDANT), was synthesized and characterized. AgDANT was prepared with a 97% yield and characterized by IR spectroscopy, single-crystal X-ray diffraction, and DTA. The crystal density of AgDANT is 2.530gcm(-3) and the molecule consists of a centro-symmetric dimer with a high degree of planarity. The intramolecular AgAg distance is relatively low (331pm) and can be considered as a strong argentophilic interaction. AgDANT is non-hygroscopic and its solubility in water (1.27mg in 100mL at 23 degrees C) is on a similar level of solubility to that of silver azide. The sensitivity of AgDANT to impact is slightly higher than that for MF, sensitivity to friction is the same as for LA, and sensitivity to electric discharge is between that for LS and MF. Initiation efficiency of AgDANT was tested in electric detonators and compared to dextrinated lead azide (initiation efficiency of AgDANT is 40mg for PETN secondary charge). The thermal resistance of detonators with AgDANT is satisfactory; all detonators were fully functional after exposure at 65 degrees C (30d) and 85 degrees C (2d).
