Description
Summary:The synthesis, characterization, and X‐ray structure of new manganese valence tautomeric complexes are reported here. The feasibility to synthesize, characterize, and study the new tautomeric complexes as stable species allowed us to establish a new switching molecular array of six states that interconvert reversibly either thermally (valence tautomerism) or by a reversible oxidation process. A molecular switch with six electronic states, all of which exhibit different optical and magnetic properties, is reported. The molecule with these unusual properties is a manganese complex with two identical tridentate ligands: it undergoes reversible one‐electron oxidation and thermal valence tautomerization, involving Mn oxidation states and radical vs. ionic ligands. The Figure shows one tautomer of the oxidized form.
