A difluorine complex is a molecular complex involving a difluorine molecule (F
2) 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 lig ...
(AuF
7).
[ 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 complex
Dihydrogen complexes are coordination complexes containing intact H2 as a ligand. They are a subset of sigma complexes. The prototypical complex is W(CO)3( PCy3)2(H2). This class of compounds represent intermediates in metal-catalyzed reactions ...
es, 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 electr ...
