Chanabayaite
Chanabayaite is the first recognized triazolate mineral, having the following formula: Cu2(NCHCl(NH,Cl,HO,[]). Minor iron admixture is also present. It is also one of a few currently known minerals containing ammine groups, including also ammineite, joanneumite and shilovite. All the minerals are rare and were found in a single guano deposit in Chile, called Pabellón de Pica. A similar natural phase, formula NaCuCl[NCH][NH]·4HO, likely a precursor of chanabayaite, is described by Zubkova et al. 2016.
