Group 12 joins the σ-hole interaction family with spodium bonds
A type of non-covalent bond has been discovered in compounds of zinc, cadmium and mercury. Coined spodium bonds, they are interactions between the elements’ σ-hole – a region of positive electrostatic potential – and a Lewis base or an anion.
