A trivacant heteropolytungstate derivative P₄W₃₀Al₄ (H₂O)₂O₁₁₃^30- has been synthesized from the lacunary precursor Na₁₂[α-P₂W₁₅O₅₆]·24H₂O and characterized by IR.polarogram and ¹⁸³W NMR spectrum.¹⁸³W NMR of the title anion consists of eight lines with intensity ratio 1:2:2:2:2:2:2:2 as expected for the dimeric Dawson-typed anion with C_2h symmetry.
