Joanneumite, confirmed as a new mineral in 2012, is the first recognized isocyanurate mineral, with the formula Cu(C3N3O3H2)2(NH3)2. Its crystal structure is identical to the structure of its synthetic analogue bis(isocyanurato)diamminecopper(II). It is an ammine-containing mineral, a feature shared with ammineite, chanabayaite and shilovite. All of these minerals are very rare and were found in a guano deposit in Pabellón de Pica, Chile.
