Xenon tetrachloride is an unstable^[1] inorganic compound with the chemical formula XeCl₄. Unlike other noble gas/halide compounds, it cannot be synthesized by simply combining the elements, by using a more-active halogenating agent, or by substitution of other halides on tetrahaloxenon compounds. Instead, a decay technique can be used, starting with K¹²⁹ICl₄. The iodine-129 atom of the ¹²⁹
ICl^–
₄ covalent cluster is radioactive and undergoes beta decay to become xenon-129.^[2]^[3] The resulting XeCl₄ molecule has a square planar molecular geometry analogous to xenon tetrafluoride.^[4]
