Abstract
Silane modified polyoxometalate anions represented by the formula YZ(SiRR').sub.n were prepared by reacting a silane having two hydrolyzable groups with a lacunary polyoxometalate anion. In the formula YZ(SiRR').sub.n, Z is M.sub.11 O.sub.39.sup.-12, M.sub.9 O.sub.34.sup.-14 or M.sub.17 O.sub.61.sup.-20, where M is tungsten or molybdenum; Y is As.sup.+5, Si.sup.+4, B.sup.+3, Ge.sup.+4, P.sup.+5 or Fe.sup.+5 when Z is M.sub.11 O.sub.39.sup.-12, Y is Si.sup.+4, Ge.sup.+4, or P.sup.+5 when Z is M.sub.9 O.sub.34.sup.-14 and Y is As.sub.2.sup.+10 or P.sub.2.sup.+10 when Z is M.sub.17 O.sub.61.sup.-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 (.dbd.SiRR').sup.+2 groups bonding to the polyoxometalate anion and has a value from 1 to 3.
