Abstract

For at least a day, stability is imparted to the light-induced, metastable, high-spin state of an iron(II) complex with a strong ligand field (see scheme) at ≥20 K. The lifetime of this state is more than eight orders of magnitude longer than that predicted by the theory of the inverse energy-gap law.
