摘要：
Molecular-based magnets with high magnetic-ordering temperatures, T(C), can be obtained by mild chemistry methods by focusing on the bimetallic and mixed-valence transition metal mu-cyanide of the Prussian blue family. A simple orbital model was used to predict the electronic structure of the metal ions required to achieve a high ordering temperature. The synthesis and magnetic properties of two compounds, [Cr5(CN)12].10H2O and Cs0.75 [Cr2.125(CN)6]-5H2O, which exhibited magnetic-ordering temperatures of 240 and 190 kelvin, respectively, are reported, together with the strategy for further work.
