A new aspect of cobalt dioxolene chemistry : The preparation and characterization of the first low‐spin cobalt(II) semiquinonate complex is described. The temperature‐induced change of the spin state in this cobalt dioxolene complex (see scheme) is linked to a spin‐crossover process rather than to valence tautomerism.
