The mixed‐valent Fe II Fe III complex 1 (structure shown on the right; the dashed line indicates a weak hydrogen bond to one ClO 4 −counterion) with the ground state S t = 1/2 is the first functional model for the mixed‐valent form of the metalloprotein hemerythrin. Like the protein, 1 disproportionates autocatalytically in CH 3 CN to the Fe II Fe II and Fe III Fe III forms. L = 1,4,7‐trimethyl‐1,4,7‐triazacyclonane.\documentclass{article}\usepackage{amssymb}\pagestyle{empty}\begin{document}$$[{\rm LFe}^{\rm II}(\mu\hbox{-OH})(\mu\hbox{-privalato})_2{\rm Fe}^{\rm III}{\rm L}]^{2+}\quad{\bf 1}$$\end{document}
