Ira Weinstock and colleagues from Ben Gurion University of the Negev have used cryogenic transmission electron microscopy to evaluate the interactions of polyoxometallates of different dimensions and shapes with gold nanoparticles. The study revealed a “face-down” orientation of the Pressyler ion [NaP5W30O110]14–, and a “tilted” orientation for the Finke-Droege ion [P4W30Zn4(H2O)2O112]16–, contributing to important ongoing studies on the design of functional-POM protected metal nanoparticles.
"Face-down" orientation of Pressyler ion maximises interactions between cluster anion and Au surface.
