Cover Feature: Homoleptic Mononuclear Tris‐Chelate Complexes of FeII, CoII, NiII, and ZnII Based on a Redox‐Active Imidazolyl‐2‐thione Ligand: Structural and Electrochemical Correlation (Eur. J. Inorg. Chem. 17/2020)

The Cover Feature shows the linear correlation between the average M–N bond length of a series of mononuclear tris‐chelate complexes and the oxidation potential of the redox‐active ligand pyridylimidazolyl‐2‐thione. The oxidation potential is predictable as the M–N bond length is proportional to the ionic radius of the metal. On the left, it is possible to observe the voltammograms of the free ligand and the metal complexes, while the crystal structure of the high‐spin iron(II) complex is on the right.
