Abstract

(Figure Presented) Back and forth: The two complexes [{P₂W ₁₅O₅₄(H₂o)₂}₂Zr] ^12- and [{P₂W₁₅o₅₄-(H ₂O)₂}Zr{P₂W₁₇O₆₁}] ^14- exhibit extensive dynamic structural changes induced by completely reversible multiple protonation behavior, comparable to the flexing of a muscle (see picture). The pH titration of the former complex indicates a two-step dissociation of all eight protons, in agreement with the structural and spectroscopic studies.
