Back Cover: Ligand‐Unsupported Cuprophilicity in the Preparation of Dodecacopper(I) Complexes and Raman Studies (Angew. Chem. Int. Ed. 31/2018)

Cuprophilicity is still under debate, while aurophilicity and argentophilicity are well recognized. I.‐C. Chen, Y.‐C. Tsai, and co‐workers report in their Communication on page 9925 ff. the synthesis and characterization of two dodecacopper(I) chain‐like complexes via intermolecular Cu–Cu coupling of two linear hexacopper monomers. Their structures were determined by X‐ray crystallography and the unsupported cuprophilic interactions were corroborated by Raman spectroscopy.
