title = "Vanadium and molybdenum disorder in M2.5VMoO8 (M = Mg, Mn, and Zn) determined with neutron powder diffraction and phase formation studies of Mg2.5+xV1+2xMo1-2xO8",
abstract = "Disorder between the vanadium and molybdenum sites was investigated using neutron diffraction on polycrystalline samples of M2.5VMoO 8 (M=Mg2+, Mn2+, Zn2+) and the distribution of V5+ and Mo6+ among the tetrahedral sites was determined to be nearly statistical. The refined structures for all three polycrystalline samples corroborate those of corresponding single crystals determined previously with X-ray single crystal diffraction. Studies directed at the formation of Mg2.5+xV1+2xMo1-2xO 8 (x=0, ±0.02 and ±0.04) demonstrate that the phase begins to form at an appreciable rate at 1173K, which is approximately 250K below its melting point.",
