    • Abstract

       

      Ln2MoO5 oxides where Ln=La, Pr, Nd, Sm, Gd, Tb, Dy, Ho and Y have been prepared by hydrogen-reduction of the corresponding Ln2MoO6 at 800–900°C. The lighter Ln2MoO5 oxides (Ln=La, Pr and Nd) crystallize in a monoclinic Yb2ReO5 structure, while the heavier ones along with the yttrium compound are formed in an anion-deficient fluorite type structure. The latter on annealing at 1200° C in vacuum also transform to the Yb2ReO5 structure type.
