caption_attribution_description: English: Dark violet crystal aggregates of joannneumite (IMA 2012-001), from Pabellon de Pica, Chanabaya, Iquique Province, Tarapacá Region, Chile. The mineral is a chemical oddity because is a mixture of two organic compounds (ammine-cianurate) and an inorganic compound (copper). It is the first organometallic mineral in Nature. Associated mineral is pale blue greenish salammoniac, on grandodiorite matrix.
context_page_description: Joanneumite, confirmed as a new mineral in 2012, is the first recognized isocyanurate mineral, with the formula Cu(C₃N₃O₃H₂)₂(NH₃)₂. It is also an ammine-containing mineral, a feature shared with ammineite, chanabayaite and shilovite. All the minerals are very rare and were found in a guano deposit in Pabellón de Pica, Chile.
