Coordination chemistry with 1-methyl-5H-tetrazole: cocrystallization, laser-ignition, lead-free primary explosives – one ligand, three goals

Numerous energetic coordination complexes (Mn^II, Fe^II, Co^II, Ni^II, Cu^II, Zn^II, and Ag^I) using 1-methyl-tetrazole as the ligand were synthesized and tuned by different counteranions (e.g. NO₃⁻, ClO₄⁻, picrate, and styphnate). They show great potential for mechanical or optical initiation systems.
