过渡元素钼钨钒磷五元杂多配合物的合成、表征以及与奎宁的取代反应

Eight new complexes were synthesized for the first time. The compounds which have the general formula K_xH₂[PM(OH₂)Mo₇W₂V₂O₃₉]·nH₂O(M=Cr³⁺，Mn²⁺，Fe³⁺，Co³⁺，Ni²⁺，Cu²⁺，Zn²⁺， Cd²⁺; x=4 or 5) were de-termined by conductance titration and elemental analysis. The analysis of IR， UV， XRD and ESR show that the products hold the Keggin structure and TG-DTA， IR， XRD at various temperatures and water solubility test also give the evidences that the range of pyrolysis temperature is 300～350℃. The study on the substitutional reaction of coordinated water by optical ligand quinine shows that the S_N2 nucleophilic substitution occures when Ni is con-tained in the compound and S_N1 nucleophilic substitution occures when Cu is contained. These also confirmed that the transitional metals are in the inner sphere of the complexes.
