en.wikipedia.org/wiki/Native_element_mineralsNative element minerals are those elements that occur in nature in uncombined form with a distinct mineral structure.The elemental class includes metals and intermetallic elements, naturally occurring alloys, semi-metals and non-metals.The Nickel–Strunz classification system also includes the naturally occurring phosphides, silicides, nitrides and carbides and arsenides
materialsproject.org/materials/mp-20738FeSi2 crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Fe is bonded in a body-centered cubic geometry to eight equivalent Si atoms. All Fe–Si bond lengths are 2.37 Å. Si is bonded in a 9-coordinate geometry to four equivalent Fe and one Si atom. The Si–Si bond length is 2.34 Å.
www.mindat.org/min-40150.htmlFirst described, without CNMMN approval as "Ferdisilicite" (FeSi2), the first described member of the Fe–Si alloy mineral series by Gevork’yan (1969). Redefined as a new mineral, revalidated with the new name linzhiite with a CNMNC approval (IMA 2010-011). Linzhiite is named for the Linzhi Prefecture, which is situated close to the type ...

(2004), hapkeite formed as a result of meteorite fall onto the Lunar regolith. Ferdisilicite (leboite) FeSi 2 is known from the sedimentary Poltava sequence in the Donyeck area (Ukraine) and the concentrates of metamorphic rocks from Longquan,
