Summary The half Wells-Dawson structure complex Na9PW8-MoO34·11H2O has been prepared by reaction of Na2WO4·2H2O, Na2MoO4·2H2O and KH2PO4 in water. A series of transition metal substituted heteropolyoxometalate complexes with ternary Keggin structures of the general formula [TBA]3H n [PW9MoM2O38 (H2O)2]·3C3H6O (TBA = tetrabutylammonium; n = 2, M = Fe3+; n = 4, M = Mn2+,Co2+,Cu2+or Zn2+), have been synthesized using Na9PW8MoO34·11H2O and the transition metal nitrate as the starting materials in aqueous solution. The compounds were characterized by elemental analyses and spectroscopy. X.p.s. data indicate that the binding energies of all the elements in the title compounds are lower than those in similar compounds. The magnetic susceptibilities of the compounds reveal antiferromagnetic properties.
