Xenon tetrachloride is an unstable[1]inorganic compound with thechemical formula XeCl4. Unlike most othernoble gas/halide compounds, it cannot besynthesized by simply combining theelements, by using a more-active halogenating agent, or bysubstitution of other halides on tetrahaloxenon compounds. Instead, adecay technique can be used, starting with K129ICl4. Theiodine-129 atom of the129
ICl–
4covalent cluster isradioactive and undergoesbeta decay to becomexenon-129.[2][3] The resulting XeCl4 molecule has asquare planar molecular geometry analogous toxenon tetrafluoride.[4]
Alternately, the product can be obtained by subjecting the elements to an electric discharge.[1]
Xenon dibromide is another noble-gas halide that can only be synthesized by thedecay technique.
