Allabogdanite is a very rare phosphide mineral with formula (Fe, Ni)2P, found in 1997 in a meteorite. It is not Radioactive. It was described as an occurrence in the Onello meteorite in the Onello River basin, Sakha Republic; Yakutia, Russia; associated with taenite, schreibersite, kamacite, graphite, and awaruite.
It occurs as thin lamellar crystals disseminated in plessite. Associated minerals are nickelphosphide, schreibersite, awaruite, and graphite. It was named for Russian geologist Alla Bogdanova.
