183WNMR SPECTRA STUOY OF THE DAWSON STRUCTURAL TUNGSTONIOBOPHOSPHATE HETEROPOLY COMPLEXES |

摘要: 迄今所见报道有关Dawson结构183WNMR已被指认的只有α-,β-P2W18O626-,α2-P2W17O6110-和α2P2W17VO627-等少数几个杂多阴离子[1],其指认是基于W-O-P偶合值的大小. |

Abstract: The studies on the 183W NMR spectra of tungstoniobophosphate and other heteropoly complexes with Dawson structure resulted in the sequence of effect of substituted atoms in“polar”sites on the chemical shifts of“equatorial' and ”polar“ tungsten atoms, called ”chemical shift order“. The 183W shifts of α2-[P2W17NbO62]7- and α-1,2,3-[P2W15Nb3O62]9- prepared by our group were assigned. |
