Structural and electrochemical data for [Cp*Rh] complexes spanning three oxidation states demonstrate that the 9,9′‐dimethyl‐4,5‐diazafluorene ligand, a notable but uncommon analogue of 2,2′‐bipyridine, can stabilize electron‐rich species through π‐backbonding and concomitant charge delocalization. This “fresh light” on the bonding properties is reflected in the photo of a recent vibrant sunset in the authors’ home city of Lawrence, Kansas. More information can be found in the Research Article by J. D. Blakemore et al. (DOI: 10.1002/chem.202103970).
