Abstract

The cover picture shows three types of nickel complexes that are stabilized by 1,1′‐bis(phosphanyl)ferrocene ligands, which can be considered as model complexes for the hypothetical metal‐mediated reaction between CO~2~ and ethylene to form acrylic acid. The (acrylic acid)nickel(0) complexes are of particular interest as they represent the first stable combination between Ni^0^ and this strong acid as a ligand. These complexes form hydrogen‐bonded dimers in the solid state and are surprisingly stable. Details of their synthesis and reactivity along with the description of the other complexes are discussed in the article by D. Walther et al. on p. 2257 ff. The artwork was created by Ulf Walther.
