摘要：
A trivacant heteropolytungstate derivative P4W30Al4(H2O)(2)O-112(20-) has been synthesized from the lacunary precursor Na-12[alpha -P2W15O55]. 24H(2)O and characterized by IR, polarogram and W-188 NMR spectrum, W-188 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.
