Abstract

POMs de terre: The combination of tungsten-containing polyoxometalate (POM) fragments with gadolinium cations results in exceptionally long polyoxotungstates. The title anion (see structure; W green, As purple, Gd blue, O red, H2O cyan) is almost 5 nm in length, resulting in a challenging solution chemistry and also new perspectives for POMs in nanochemistry.
