Abstract: Two series of twelve title complexes were synthesized for the first time.Their general molecular formulas were determined as:K9,10[(P2M(H2O) W15V2O61]·xH2Oand K10,11[P2M(H2O)W14V3O61]·xH2O(M= Fe3+,Co3+,Ni2+,Mn2+,Cu2+,Zn2+).The data of IR, UVspectra of all the products and their characteristic absorption peaks were provided.Especially for the compounds with phosphorus as the central atom, the relationship between the structure and chemical shift was explained by means of 31P and 51V NMR spectra.ESRspectra were used to explain their electronic features.The X-ray diffraction data indicate that all the complexes still remain basically characteristic of the Dawson structure.The stabilities of heteropoly complexes were also studied simultaneously.
Key words: Transition elements, Heteropolytungstovanadophosphate, Dawson structure
