Abstract: The isomers of K13[Ln(α-,β2-SiW11O39)2]· xH2O(Ln=La,Ce,Pr,Nd,Sm,Gd,Er) were prepared, and characterized by elemental analysis, polarography, CV,UV,Vis,IR and 29SiNMR spectra, magnetic moments and thermal analysis. Their stabilities and relationship between the properties and structure are discussed.

Key words: Lanthanide elements, Heteropoly tungstosilicate complex, Heteroply acid isomer
