β¦ Synopsis
Microstructure and Thermal Stability of a Series of Molecular Oxides. -Heteropolymolybdate salts of composition CsxH 4-x PVMo 11 O 40 β’nH 2 O (0 β€ x β€ 4) precipitate from aqueous solutions of Cs 2 CO 3 and H 4 PVMo 11 O 40 . The Cs salts (2 β€ x β€ 4) have a simple cubic structure, space group Pn3m, as determined by powder XRD. The free acid exhibits a triclinic lattice (space group P-1) for the majority of all crystals and a simple cubic lattice (Pn3m) for a minor fraction of thin crystals. Computer simulation of the XRD pattern suggest that the structure of Cs 2 H 2 PVMo 11 O 40 β’5H 2 O contains defects in the cation lattice.
