[Cp*Ru(acac)] Is Not a Coordinatively Unsaturated, Stable 16‐Valence‐Electron Complex

The bent structure of [C5Me5Ru(acac)] in the solid state (Hacac = acetylacetone) arises from the interaction of the ruthenium center with the γ‐carbon atom of the acac ligand of a second, symmetry‐equivalent molecule of [C5Me5Ru(acac)] and is not an intrinsic characteristic of the complex as claimed by Kölle et al. in 1990 in a communication in this journal. Reinterpretation of the X‐ray data provided these results.
