Inside Cover: New Experimental Insight into the Nature of Metal−Metal Bonds in Digallium Compounds: J Coupling between Quadrupolar Nuclei (Chem. Eur. J. 28/2016).

Direct insight into the elusive nature of multiple bonding between gallium atoms in molecular solids is obtained with ultrahigh ‐ field two ‐ dimensional 71Ga NMR spectroscopy. The gallium – gallium J couplings offer a novel perspective on the electronic structure of these bonds, and the intriguing results are discussed in the context of analogous data for carbon−carbon and boron−boron spin pairs.
