The Brechin group has published a paper in Angew. Chem. Int. Ed., in which they describe a very simple synthetic strategy for producing molecular analogues of bulk iron oxides such as magnetite.
Magnetic data, measured at temperatures as low as 0.4 K and fields up to 35 T, in tandem with theoretical calculations, reveal unusual spin frustration effects. Structural similarities to polyoxometalates (POMs) hints that a diverse family of novel Fe(III) molecular metal oxides awaits discovery, with the methodology suggesting an exciting route to the bottom-up assembly of molecular metal oxide ‘nanoparticles‘ with a raft of potential applications.
