Comment on "Observation of Alkaline Earth Complexes M(CO) (M = Ca, Sr, or Ba) That Mimic Transition Metals"
Affiliations
Wu (Reports, 31 August 2018, p. 912) claim that recently characterized octacarbonyls of Ca, Sr, and Ba mimic the classical Dewar-Chatt-Duncanson bonding motif of transition metals. This claim, which contradicts known chemistry and computed electron density distributions, originates in the assumption of a flawed reference state for energy decomposition analyses.
