Remarkable thermal stability is exhibited by [FeII(tcne)2]⋅x CH2Cl2 (57Fe Mössbauer spectra reveal that the oxidation state of iron is II), which was prepared by treating the MeCN solvate of FeI2 with tetracyanoethylene (TCNE). This method, which can also be applied to synthesize the analogous Mn, Co, and Ni compounds, provides a simple route to novel molecule-based magnets with interesting properties.
