Methylated ammonium and hydrazinium salts of 5,5 '-azotetrazolate

Salts of the 5,5'-azotetrazolate dianion with methylated ammonium and hydra zinium cations were prepared. The compounds were characterized by elemental analysis, vibrational (IR, Raman) and multinuclear NMR spectroscopy (H-1, C-13, N-14). The crystal structures of the di[ammonium], the bis[dimethylam monium] and the bis[trimethylhydrazinium] 5,5'-azotetrazolate salts were de termined. The thermal, shock and friction sensitivities of these compounds were investigated and their explosion products were analysed.
