Designing Cyanide-Bridged Single Molecule Magnets

Abstract

Cyanide-bridged metal complexes, which originated from Prussian blue analogues known for their functions as pigments, optical and magnetic materials, and electrode batteries, are representative molecular magnets that can be designed. Research on these molecular magnets has shifted focus from the realization of ferromagnetic superexchange interactions to external field response, multi-physical properties, and, in recent years, single-molecule magnets as nanomagnets. This review collects examples of cyanide-bridged single-molecule magnets. In addition to the accumulation of experimental data, we also discuss the possibility of molecular design and prediction using computational chemistry based on crystal structure data.
