Difluorine complex

A difluorine complex is a molecular complex involving a difluorine molecule (F2) and another molecule. The first example was gold heptafluoride (AuF7).[1] 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.[2]
