摘要
A trisubstituted Dawson anion,with tetravalent heteroelement titanium has been synthesized from the lacunary Precursor Na12[α-P2W15O56].24H2O and characterized by IR. UV.and 183W NMR Spectrum. 183W.NMR of the title ation consists of three lines(intensity ratio 1:2:2) as expected for the trisubstituted. Dawson anion.
