Name:
Named in honor of Hans-Peter Bojar (b. 1967), Department of Mineralogy, Universalmuseum Joanneum, Graz. He is a geoscientist who works interdisciplinary in many earth science research areas. He is the senior author of the discoveries of several new mineral species, including two N- and Cu-bearing minerals from Pabellón de Pica Mountain, ammineite and joanneumite.
New structure type.
Third natural crystalline triazolate after chanabayaite and triazolite. Also compare pabellóndepicaite.
Awarded 'Mineral of the Year' by the IMA-CNMNC in 2020.
