Tetra Xenono Gold
From Wikipedia, the free encyclopedia
Tetra Xenono Gold(II) or AuXe42+ is a cation with a square planar configuration of atoms. It is found in the compound AuXe42+(Sb2F11-)2. The AuXe42+ ion is stabilised by interactions with the fluoride atoms of the counterion. Tetra Xenono Gold(II) is unusual in that it is a compound of the notoriously inert atoms xenon and gold. It is also unusual in that it uses xenon as a transition metal ligand. It can be produced by reduction of AuF3 in the presence of fluoroantimonic acid and xenon, and crystallised at low temperature.
