5-nitrotetrazolate anions were synthesized and characterized. On the basis of experimentally obtained heats of
combustion, the calculated heats of formation range from ΔHf° = 80 (3) to 1071 kJ/mol (13). Imidazolate salts are
more dense but have lower heats of formation than their tetrazolate analogues. Salts 4, 5, 8, and 11−14 fall into
the ionic liquid class (mp < 100 °C). The structure of 1,2,4-triazolium 5-nitrotetrazolate (10) was confirmed by X-ray
analysis.
