The reaction of the WO4(2-) ion in the pH range 2 to 8 was carried out with the following metal ions individually in combination: Mn2+, Mn3+, Fe2+, Fe3+, Co2+, Co3+, Ni2+, Cu1+, Cu2+, Zn2+, Ga3+, Mg2+, In3+, RAsO3(2-), RSbO3(2-). Some 36 heteropolyanions have been isolated in the crystalline form characterized fully. The antiviral activity of these anions has been determined against HIV, herpes...
