Dihydrogen bond

A dihydrogen bond is a type of non-covalent interaction that occurs between molecules where a hydrogen atom covalently bonded to an electronegative atom (such as oxygen, nitrogen, or fluorine) interacts with another hydrogen atom that is covalently bonded to a similar electronegative atom in a different molecule. This interaction is crucial in some specific molecular arrangements, particularly in the context of hydrogen-rich compounds or in environments where multiple hydrogen bonds can influence the molecular structure.
