| Abstract: Eight new complexes were synthesized for the first time. The compounds which have the general formula KxH2[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 SN2 nucleophilic substitution occures when Ni is con-tained in the compound and SN1 nucleophilic substitution occures when Cu is contained. These also confirmed that the transitional metals are in the inner sphere of the complexes. | |
