The side reactions in the anionic polymerization of (meth)acrylates initiated by organolithium compounds raise the question about favorable interactions between organolithium and carbonyl compounds in general and in this polymerization reaction. The results of several crystal structures of lithium(sodium) (ester) enolates without or with other molecules clearly demonstrate the favorable formation of homo‐ and mixed aggregates, respectively. It is also shown how different gegenions (ZnBr + , R 4 N + , etc.) influence the overall structure and the structure of the anion.
