Abstract

The syntheses, structural characterization, and catalytic properties of two different nickel-containing polyoxometalates (POMs) are presented. The dinickel-containing sandwich-type POM [Ni₂(P₂W₁₅O₅₆)₂]^20- (Ni₂) exhibits an unusual αααα geometry. The trinickel-containing Wells-Dawson POM [Ni₃(OH)₃(H₂O)₃P₂W₁₆O₅₉]^9- (Ni₃) shows a unique structure where the [α-P₂W₁₅O₅₆]^12- ligand is capped by a triangular Ni₃O₁₃ unit and a WO₆ octahedron. Ni₃ shows a high catalytic activity for visible-light-driven hydrogen evolution, while the activity for Ni₂ is minimal. An analysis of the structures of multinickel-containing POMs and their hydrogen evolution activity is given.
