Some 5,5'-azotetrazolate salts, via double displacement of sodium 5,5'-azotetrazolate.
The cadmium salt was attempted, the reaction failed as the pH of the cadmium nitrate solution was too high or contained too much dissolved
NO2 and the 5,5'-azotetrazolate decomposed.
The ammonium salt was attempted, the reaction failed to produce a precipitate and when taken to dryness decomposed.
