Structure of the cerium molybdenum anion (CeMo/sub 12/O/sub 42/)/sup 8 -/, for which a high coordination number of the central atom (12) and combination of MoO/sub 6/ octahedra along the faces are characteristic, was given for the first time in a brief communication for the example of the salt (NH/sub 4/)/sub 2/H/sub 6/(CeMo/sub 12/O/sub 42/).12H/sub 2/O. Later the crystal structures of the copper salt of uranium molybdenum acid and its complexes with Er/sup 3 +/ and Th/sup 4 +/ anions were determined. This work is devoted to the x-ray structural study of the cerium molybdenum (CMA) and uranium molybdenum (UMA) heteropoly acids (HPA). A short distance between oxygen atoms of two neighboring polyanions has been found, which allows the suggestion of the presence of a hydrogen bond between them. Distribution of the water molecules in the crystals of the acids is statistical.
