By the application of newer preparative methods and specific organic cations single crystals of polymetallates were obtained of till now unknown structural types. These are salts with polyanions W6O192-, W10O324-, [HW12O38(OH)2]5-, Mo6O192- and HV4O123-, furthermore para-tungstates A and B, as well as the compounds [N(CH)3)4]2 Μο8Ο25·5Η2Ο and [N(CH3)4]2Mo10 O31 · 7H2O. The structures of the anions W6O192- and W10O324- were elucidated by X-Ray analyses; the structure of the Μο6Ο192- was derived by vibrational spectroscopy. The knowledge of newer polyanion structures increasingly enables us to gain an insight into the complicated mechanism of oxyhydrate formation by acidification of metal salt solutions.

Keywords: Polymetallates; preparative methods; vibrational spectra
