Abstract: The reaction of[KAs4W10O140(M·H2O)]n-(M=Mn2+,Co2+,Ni2+,Cu2+ or Cr2+)anions in toluene is reported.The coordinated water molecules of the title anions can not be substituted by SCN-,Py in aqueous solution.However,she same replacement reaction takes easily in toluene.Some of the title anions can lose the coordinated water molecules directly leading to coordmatively unsaturated site on the surface of the anions in toluene.Synthesis and oxidation properly of the high oxidation state complexes are also reported.

Key words: Heteropoly tungstoarsenate anion, Synthesis, Oxidation property
