Ammineite
Ammineite is the first recognized mineral containing ammine groups. Its formula is [CuCl(NH)]. The mineral is chemically pure. It was found in a guano deposit in Chile. At the same site other ammine-containing minerals were later found:
- Chanabayaite, CuCl(NCH)(NH)ยท0.25HO (an alternative formula), a triazolate mineral
- Joanneumite, Cu(CNOH)(NH), an isocyanurate mineral
- Shilovite, Cu(NH)(NO)
