Abstract

Polyoxometalate (POM) anions were successfully integrated into Fe(II) spin crossover (SCO) system, which demonstrates an effective role in regulating spin-state switching properties. Specifically, three drastically different magnetic behaviors of Fe(II) ion in the identical cation [Fe(bpp)₂]²⁺ were achieved by leveraging [Mo₆O₁₉]^2-, [Mo₈O₂₆]^4-, and [Na(Mo₈O₂₆)]^3-, respectively.
