New Molecule-Based Magnets: From Hexacyano to Octacyanometalates

Abstract
Prussian blue molecule-based magnets can be designed to exhibit various magnetic properties. One of them based on chromicyanide and vanadium is a magnet at room temperature. Its properties are very sensitive to the synthetic reaction conditions, solvent effects and counterions which can be used to tune the Tc. To study the interaction between nearest metallic neighbours we explore also the influence of diffuse and high energy magnetic orbitals, i.e. 4d or 5d metallic orbitals. Two derivatives of [Wv(CN)8]3- are presented.
