Description

The crystal structures of cerium-molybdic and uraniummolybdic heteropolyacids are determined at first. The parameters of hexagonal double centred lattice in the rhombohedral system (space group R anti 3) make up: for the HPA Ce (IV) a=10.774(7) A, ν=81.11 (5) deg, V=1210 A3, Z=1, dsub(cal)=3.07 g/cm3; for the HPA U (IV) a=10.777(7) A, ν=81.14 (5) deg, V=1211 A3, Z=1, dsub(cal)=3.27 g/cm3. The short distance between the oxygen atoms of the two neighbour polyanions is found; that permits to suppose the presence of hydrogen bond between them. The arrangement of water molecules in crystals is statistical
