【Abstract】 Two series of twelve title complexes were synthesized for the first time. Their general molecular formulas were determined as:K_{9, 10}[(P₂M（H₂O） W₁₅V₂O₆₁]·xH₂O and K_{10, 11}[P₂M（H₂O）W₁₄V₃O₆₁]·xH₂O(M= Fe￣（3+）,Co￣（3+）,Ni₂₊,Mn₂₊,Cu₂₊,Zn₂₊). The data of IR, UV spectra 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￣（31）P and ￣（51）V NMR spectra. ESR spectra 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.更多还原
