What is it about?
Polyoxometalates (POMs) are an important class of inorganic clusters with wide range of applications in chemistry. But how do they crystallize? The answer to this question remains enigmatic. In this paper we show that crystallization of POMs is a phase transition from colloidal soft-oxometalates (SOMs). We use extensive phase study and Mueller Matrix Polarimetry to confirm our observation.

Why is it important?
With this work we show that in principle any oxometalate can be crystallized provided we are in the right regime of concentration of the salts, ionic strength (counter-ions) and osmotic compressibility. It is the first step towards crystal engineering of Polyoxometalates (POMs) which we show proceed via the mediation of the colloidal SOM state.
