Zinc-Zinc Bonds: A New Frontier

Some metals readily form bonds to other atoms of the same element in molecular compounds, but others, such as zinc, are not known to do so. In his Perspective, [Parkin][1] highlights the discovery of a molecular compound with a zinc-zinc bond by [ Resa et al .][2] and places the discovery in the context of the other two elements in group 12 of the periodic table, cadmium and mercury.
