In chemistry, a pentazolate is a compound that contains a cyclo-N5− ion, the anion of pentazole.

In 2017, researchers prepared the first salt (N5)6(H3O)3(NH4)4Cl containing pentazolate anion starting a substituted phenylpentazole, m-CPBA and iron(II) glycinate.

[1] A series of metal and nonmetal pentazolates were subsequently synthesized according to their work.
