The preparation of eleven heteropolytungstate anions, X2ZW17O62H2x–(X = P or As; Z = Mn, Co, Ni, or Zn) is described. These include the first heteropolyanions with MnIII as heteroatom. The stabilities of the anions towards acid and base, and the redox potentials and magnetic moments of the Z heteroatoms are reported, and the formulation of the anions and their spectra are discussed.
