Named in honor of Professor Nikolai Stefanovich Bortnikov (Николай Стефанович Бортников) (b. 25 March 1946, Bolshaya Kazinka, Voronezh Region, USSR), prominent Russian mineralogist and researcher of ore deposits and a corresponding member of the Russian Academy of Sciences. He was Director of the Institute of Geology of Ore Deposits, Petrography, Mineralogy and Geochemistry of the Russian Academy of Science (now IGEM).

Type Locality:

ⓘ Konder alkaline-ultrabasic massif, Ayan-Maya district, Khabarovsk Krai, Russia

The first platinum group mineral that contains Zn as a major mineral-forming element. Its origin is related to the effect of alkaline fluid on ultramafic rocks.
