Resumo
Neodymium molybdate with a cubic fluorite-like structure was obtained by solid state reactions from metal oxides. The formation of the final product occurs through the formation of a monoclinic structure of Ln2MoO6 type (space group C2/c) at 700°C, which probably contains vacancies in neodymium and oxygen lattices. Neodymium molybdate obtained at 900°C crystallizes in the space group Pn\(\bar {3}\)n with the cell parameter a ≈ 11.039 Å. The crystal structure of neodymium molybdate obtained at 700 and 900°C was studied by neutron diffraction and atomistic modeling using the GULP program in the pressure range 0–5.9 GPa, which demonstrated the stability of the cubic structure at elevated pressure.
