Abstract
AbstractThe yttrium containing isopolytungstate [YW10O36]9− (1) has been synthesized and isolated in the form of its hydrated sodium salt Na9[YW10O36]·35H2O (Na‐1). The title compound has been structurally characterized in the solid state by single‐crystal X‐ray crystallography, IR spectroscopy, thermogravimetric analysis and in solution by 183W and 89Y NMR spectroscopy. The X‐ray analysis shows that Na‐1 crystallizes in the triclinic system, space group $P{\bar 1}$, with a = 12.7625(9), b = 13.0825(10), c = 20.496(2) Å, α = 82.856(5), β = 74.520(4), γ = 88.822(4)°, V = 3272.1(4) Å3 and Z = 2. Solution 183W NMR shows the expected 2 lines at –1.3 ppm and –14.3 ppm, respectively, with an intensity ratio of 1:4, and 89Y NMR shows a singlet at –12.9 ppm.
