Recent Advances in the Field of Main‐Group Mono‐ and Diatomic “Allotropes” Stabilised by Neutral Ligands

The study of ligand stabilised mono‐ and diatomic zero oxidation state complexes is a young and fascinating topic. This area merges the fields of low‐oxidation‐state main‐group chemistry, homoatomic multiple bonding and fundamental coordination chemistry. As with a great deal of recent coordination chemistry within the d‐block, carbene ligands are clearly the star of the show, highlighting their importance within the p‐block as well. This Minireview focuses on the significant developments of the past two years.
