Joanneumite, confirmed as a new mineral in 2012, is the first recognized isocyanurate mineral, with the formula Cu(C3N3O3H2)2(NH3)2.[4][5] It is also an ammine-containing mineral, a feature shared with ammineite, chanabayaite and shilovite.[6][7][8] All the minerals are very rare and were found in a guano deposit in Pabellón de Pica, Chile.[9]
