Silane modified polyoxometalate anions represented by the formula YZ(SiRR')n were prepared by reacting a silane having two hydrolyzable groups with a lacunary polyoxometalate anion. In the formula YZ(SiRR')n, Z is M11O39-12, M9O34-14 or M17O61-20, where M is tungsten or molybdenum; Y is As+5, Si+4, B+3, Ge+4, P+5 or Fe+5 when Z is M11O39-12, Y is Si+4, Ge+4, or P+5 when Z is M9O34-14 and Y is As2+10 or P2+10 when Z is M17O61-20; R is selected from the group consisting of monovalent hydrocarbon radicals having from 1 to 24 carbon atoms, monovalent halogenated hydrocarbon or carbon radicals having from 1 to 24 carbon atoms and monovalent hydrocarbon radicals having from 1 to 24 carbon atoms substituted with an epoxy group, an amino group, a mercapto group or a methacrylo group; R' is a hydrogen atom or R and n represents the number of (=SiRR')+2 groups bonding to the polyoxometalate anion and has a value from 1 to 3.
