Formula: NaCu₂(N₃C₂H₂)₂(NH₃)₂Cl₃.4H₂O
Valence: NaCu²⁺₂(N₃C₂H₂)^1-₂(N^3-H₃)₂Cl₃.4H₂O
Organic compound. One of the few minerals to contain the triazolate anion (C₂H₂N₃)^1-. It also contains the ammine complex, which is a metal in complex with N^3-H₃. As of September 2023 there were five known ammine complex bearing minerals, triazolite, chanabayaite, joanneumite, ammineite and shilovite (Mindat).

Environments

Guano deposits

Triazolite was approved in 2017, but to date (July 2025) it has been reported only from the type locality.

Localities

At the type locality, Pabellón de Pica, Chanabaya, Iquique Province, Tarapacá, Chile, triazolite is found in a guano deposit. Associated minerals include salammoniac, halite, dittmarite, joanneumite, chanabayaite, nitratine, natroxalate and möhnite. Triazolite occurs as deep blue prismatic crystals up to 0.1 mm × 0.15 mm × 0.75 mm and their radial aggregates up to 1.5 mm across (MM 82.4.1007–1014).
