Abstract

The ammonium salt of the mixed-valence fluorinated heteropoly anion, [Fe3+ZnW6+ 10W5+O36F4]6−, has been prepared in the crystalline form. Evidence from X-ray powder pattens, FABMS, cyclic voltammetry, and spectroscopy (VIS, IR) has shown that the anion has the Keggin structure. It is likely that the Zn(II) ion occupies the central tetrahedral cavity of the Keggin structure and the Fe3+ ion occupies the octahedral site vacated by the missing W(VI) ion. The molecular weight of the anhydrous, deaminated compound as found by FABMS is 2779.9 da.
