The ability to tune the steric envelope through redox events post-synthetically or in tandem with other chemical processes is a powerful tool that could assist in enabling new catalytic methodologies and understanding potential pitfalls in ligand design. The α-diimine ligand, dmp-BIAN, exhibits the peculiar and previously unreported feature of varying steric profiles depending on oxidation state when paired with a main group element. A study of the factors that give rise to this behaviour as well as its impact on the incorporation of other ligands is performed.
