Abstract

Novel Keggin anions with covalently bonding pendant surface ligands, formulated as [SiW₁₁O₃₉M(H₃P₂O₇)]⁷⁻, (M = Mn^II, Co^II, Ni^II and Zn^II), were synthesized, and characterized by elemental analyses and IR, CV and NMR physical measurements. The novel complexes are expected to have the ability to anchor the clusters on supports via terminal phosphato group–support linkages.
