Single-crystal structure of vanadium-doped Nd5Mo3O16

The single-crystal structures of the oxygen-ion-conducting fluorite-type compounds Nd5Mo2.90V0.10O15.3 and Nd5Mo2.76V0.24O15.5 were determined by X-ray diffraction. It was found that the displacements of atoms in the structure are retained after the doping of these compounds with vanadium. The dopant atoms occupy the molybdenum sites. The X-ray diffraction data were used to calculate the activation energies and analyze the possible pathways for the oxygen ion migration in the structures.
