Hydromelonic acid, is an elusive chemical compound with formula C9H3N13 or (HNCN)3(C6N7), whose molecule would consist of a heptazine H3(C6N7) molecule, with three cyanamido groups H–N=C=N– or N≡C–NH– substituted for the hydrogen atoms. The compound had not been properly isolated as of 2010, due to its tendency to polymerize. However, removal of three protons yields the melonate (formerly hydromelonate) anion (NCN)3(C6N7)3−, whose salts are stable and have been known since the 19th century. Removal of only two protons yields the divalent hydrogenmelonate anion H(NCN)3(C6N7)2−.
