Pentazolate
In chemistry, a pentazolate is a compound that contains a cyclo-N5− ion, the anion of pentazole. In 2017, researchers prepared the first salt 634Cl containing pentazolate anion starting a substituted phenylpentazole, m-CPBA and iron(II) glycinate. A series of metal and nonmetal pentazolates were subsequently synthesized according to their work.
