Abstract: In this paper, a serie of multicomponent substitued polyoxometalate clusters containing silicon, tungsten, molybdenum and earlier transition metal elements were synthesized. The genetal moleculat formulat was determined: K₄H₂[M(OH₂)SiMo₂W₉O₃₉].nH₂O (M=Mn²⁺,Co²⁺,Ni²⁺,Cu²⁺, Zn²⁺, Cd²⁺; n=21-26). By means of IR,UV,XPS,TG-DTA, the properties and structural characteristics of the new tungstomolybdosilic multicomponent polyoxometalate clusters with transition elements were investigated.

Key words: tungstomolybdosilicate, transition elements , polyoxometalate clusters, tungstomolybdosilicate, transition elements
