Allabogdanite is a very rare phosphide mineral with formula (Fe,Ni)2P, found in 1997 in a meteorite.[3][1] It was described for an occurrence in the Onello meteorite in the Onello River basin, Sakha Republic; Yakutia, Russia; associated with taenite, schreibersite, kamacite, graphite and awaruite.[1] It was named for Russian geologist Alla Bogdanova.[2]
