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. The AuXe²⁺
₄ ion is stabilised by interactions with the fluoride atoms of the counterion. The Au-Xe bond length is 274 pm.

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. The xenon bonds with the gold(II) ion to make this complex.
