“SOFT OXOMETALATES” (SOMs): A VERY SHORT INTRODUCTION

Abstract

The field of polyoxometalates (POMs),^{[ 1 ]} in recent times, has entered a new arena of “soft”-supramolecular interactions, crossing the molecular regime of covalent bonds. The structures resulting from such “soft”-supramolecular interactions are much larger (∼10–500 nm in diameter), showing soft-matter properties. This comment proposes to name them “soft” oxometalates. The comment, after introducing and archiving seminal examples of soft oxometalates, gives a few examples from the author's work where soft oxometalates are generated spontaneously and those designed by deliberate chemical reactions (also followed by very few selected examples from the literature). The comment ends with an open question: are all POMs soft?
