Tetraxenonogold(II), gold tetraxenide(II) or AuXe2+
4 is a cationic complex with a square planar configuration of atoms. It is found in the compound AuXe2+
4(Sb
2F−
11)
2, which exists in triclinic and tetragonal crystal modifications.[1] The AuXe2+
4 ion is stabilised by interactions with the fluoride atoms of the counterion. The Au-Xe bond length is 274 pm.[2][3]
Tetraxenonogold(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, and in that it contains gold in the +2 oxidation state. It can be produced by reduction of AuF3 in the presence of fluoroantimonic acid and xenon, and crystallised at low temperature.[4] The xenon bonds with the gold(II) ion to make this complex.
