Synthesis and Structure of Hexatungstochromate(III), [H3Cr(III)W6O24]6-.
The hexatungstochromate(III) [H(3)Cr(III)W(6)O(24)](6-) (1) was synthesized in aqueous, basic medium by simple reaction of chromium(III) nitrate nonahydrate and sodium tungstate dihydrate in a 1:6 ratio. Polyanion 1 represents the first Anderson-Evans type heteropolytungstate with a trivalent hetero element. The sodium salt of 1 with the formula Na(6)[H(3)Cr(III)W(6)O(24)]·22H(2)O (1a) was fully characterized in the solid state by single crystal XRD, FT-IR spectroscopy, and thermogravimetric analysis.
