A difluorine complex is a molecular complex involving a difluorine molecule (F₂) and another molecule. The first example was

gold heptafluoride Gold heptafluoride is a gold(V) compound with the empirical formula AuF7. The synthesis of this compound was first reported in 1986. However, current calculations suggest that the structure of the synthesized molecule was actually a difluorine li ...

(AuF₇). Instead of being a gold(VII) compound, AuF₇ is an adduct of gold pentafluoride (AuF₅) and F₂. This conclusion has been repeatedly supported by calculations. Unlike dihydrogen complexes, which feature η²-H₂, difluorine complexes feature "end-on" or η¹-F₂

ligand In coordination chemistry, a ligand is an ion or molecule (functional group) that binds to a central metal atom to form a coordination complex. The bonding with the metal generally involves formal donation of one or more of the ligand's elect ...
