1?Amino?5?methyltetrazole in Energetic 3 d Transition Metal Complexes – Ligand Design for Future Primary Explosives

New lead-free primary explosives are needed for safe future ignition and initiation applications. Especially, by low-energy laser irradiation has been demonstrated to be a valuable method. For this technology, with safer sensitivities needed. In order adjust the desired properties of neat explosives, we follow concept “energetic coordination compounds” (ECC) in which ligand significantly alters final properties. As result study where 1-amino-5H-tetrazole (1-AT) was used as one most endothermic ligands, yielding materials outstanding performance but very high sensitivities, work its 5-methyl analogue 1-amino-5-methyltetrazole (1-AMT, 1) synthesized applied ligand. short evaluation, metal perchlorate complexes [M(1-AMT)6](ClO4)2 manganese(II), iron(II), zinc(II) well [Cu(1-AMT)4(H2O)](ClO4)2 were prepared. All compounds intensively characterized e. g., XRD, IR, EA, TGA, DTA sensitivity measurements (impact, friction, BDIS, ESD). The obtained show reduced they handle than corresponding 1-AT derivatives. Moreover, satisfactory performances ECC 3 4 impressively PETN experiments.
