Solvent induced reversible change of magnetic properties in a Fe(II)–Fe(III) single chain magnet

A single chain magnet (SCM), catena-[FeII(ClO4)2{FeIII(bpca)2}]ClO4 (1) includes three nitromethane molecules per a Fe(II)–Fe(III) unit as crystallized solvent which occupy the pores surrounded by four chains. Compound 1 can release or reabsorb these MeNO2 molecules like “sponges” possessing the chain structure of 1, accompanied by a reversible changing of SCM behavior during this process. Compound 1 is the first nano-magnet which shows the solvent induced reversible change of magnetic properties.

Crystals of single chain magnet (SCM), catena-[FeII(ClO4)2{FeIII(bpca)2}]ClO4 (1), include CH3NO2 molecules as crystallized solvent, which can be released or reabsorbed accompanied by a reversible changing of SCM behavior during this process. Compound 1 is the first nano-magnet which shows the solvent induced reversible change of magnetic properties.Figure optionsDownload as PowerPoint slide
