Potassium 1,1′-dinitramino-5,5′-bitetrazolate is one of the most promising primary explosives which is currently under investigation for different applications. This is due to its high initiation power and the exclusion of heavy metals. To close the gap, the remaining alkali metal salts such as the lithium 6 , sodium 7 , rubidium 8 and cesium 9 salts were synthesized by reaction of the highly soluble ammonium salt 5 with its corresponding metal hydroxide solutions. In addition, the highly explosive silver salt 10 as well as several other transition metal( ii ) amine complexes with nickel( ii ) 11 , copper( ii ) 12 and zinc( ii ) 13 were prepared in a similar manner. The structure of all compounds was determined by X-ray diffraction. The sensitivities toward impact, friction, heat and electrostatic discharge as well as their behavior on laser irradiation of the transition metal complexes were explored. The moment of detonation during a hot plate test of highly energetic sodium 1,1′-dinitramino-5,5′-bitetrazolate, the representative of the synthesized alkaline and transition metal salts which are very sensitive toward friction, impact heat and partly also susceptible to laser irradiation.
