The yttrium containing isopolytungstate [YW 10 O 36 ] 9− ( 1 ) has been synthesized and isolated in the form of its hydrated sodium salt Na 9 [YW 10 O 36 ]·35H 2 O ( 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 183 W and 89 Y 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) Å 3 and Z = 2. Solution 183 W NMR shows the expected 2 lines at –1.3 ppm and –14.3 ppm, respectively, with an intensity ratio of 1:4, and 89 Y NMR shows a singlet at –12.9 ppm.
