Hexamolybdenum is a molybdenum dominant alloy discovered during a nanomineralogy investigation of the Allende meteorite.[4] Hexamolybdenum was discovered in a small ultrarefractory inclusion within the Allende meteorite.[4] This inclusion has been named ACM-1.[4] Hexamolybdenum is hexagonal, with a calculated density of 11.90 g/cm3.[4] The new mineral was found along with allendeite.[4] These minerals, are believed to demonstrate conditions during the early stages of the Solar System, as is the case with many CV3 carbonaceous chondrites such as the Allende meteorite.[4] Hexamolybdenum lies on a continuum of high-temperature alloys that are found in meteorites and allows a link between osmium, ruthenium, and iron rich meteoritic alloys.[4] The name hexamolybdenum refers to the crystal symmetry (primitive hexagonal) and the molybdenum rich composition.[4] The Allende meteorite fell in 1969 near Pueblito de Allende, Chihuahua, Mexico.[4]
