Ognitite is a very rare mineral with the chemical composition NiBiTe, i.e. it consists of equal parts of nickel , bismuth and tellurium .
Etymology and history
Ognitit was first found in 2019 by the Russian geologist Gennadi Schwedow together with colleagues from other countries near Ognit ( Irkutsk Oblast ) in Siberia and named after its type locality .
The type material of the mineral is in the mineralogical collection of the Museo di Storia Naturale (Florence) under the catalog no. 3292 / I and is referenced via the IMA number 2018-006a.
Chemism
Ognitite is a sulfide salt and consists of 52.87 percent bismuth , 32.28 percent tellurium and 14.85 percent nickel .
Crystal structure
Ognitite crystallizes trigonal in the space group P 3 m 1 (space group number 156) with the lattice parameters a = 3.9332 (4) Å and c = 5.3920 (6) Å.
