Halogen bond has received widespread attention in recent years due to the vast applications in supramolecular chemistry, sensing and crystal engineering. In contrast to the normal halogen bonds, [N–I–N] type halogen bond exhibits enhanced strength and solvent resistance capabilities. It adopts a bonding geometry of the three-center four-electron bond, where the nitrogen can be a neutral, positive, or negative species such as pyridine, saccharin, and urotropine moieties. The emerging new type halogen bond has found specific potentials in constructing supramolecular architectures and catalysis. This concept provides a brief summary based on recent developments of [N–I–N] type halogen bonding, reviewing and summarizing its synthesis, structure and application.
