A novel twist in temperature-induced switching of electronic states in cobalt dioxolene complexes: Structural, magnetic, and spectroscopic results demonstrate that valence tautomerism can occur by converting a cobalt(III) catecholate into a low-spin cobalt(II) semiquinonate complex instead of the usual high-spin complex.
