<b>The Synthesis of XeF<sub>2</sub>; a Predictable Outcome with a Significant Chemistry</b>

“…Pauling and von Antropoff were the first to propose that the so-called “noble” gases could, in fact, be coerced to bond with other elements. − Yet, their reactivity was not observed in the laboratory until the synthesis of the first xenon compounds in the summer of 1962: XePtF 6 was made by Bartlett, XeF 2 by Hoppe, and XeF 4 by Claassen . The simple binary fluorides XeF 2 , XeF 4 , and XeF 6 assume linear, square planar, and octahedral coordination.…”

“…XeF 2 is the easiest noble-gas fluoride that can be handled and synthesized in high purity . High level quantum chemical calculations yield heats of formation of −23.3 and −23.9 kcal/mol at 0 and 298 K, respectively, for the gas phase species .…”

Crystal Structures and Electronic Properties of Xe–Cl Compounds at High Pressure

Crystal structure prediction techniques coupled with enthalpies obtained at 0 K from density functional theory calculations suggest that pressure can be used to stabilize the chlorides of xenon. In particular, XeCl and XeCl 2 were calculated to become metastable by 10 GPa and thermodynamically stable with respect to the elemental phases by 60 GPa. Whereas at low pressures Cl 2 dimers were found in the stable phases, zigzag Cl chains were present in Cmcm XeCl at 60 GPa and atomistic chlorine comprised P6 3 /mmc XeCl and Fd3̅ m XeCl 2 at 100 GPa. A XeCl 4 phase that was metastable at 100 GPa contained monomers, dimers, and trimers of chlorine. XeCl, XeCl 2 , and XeCl 4 were metallic at 100 GPa, and at this pressure they were predicted to be superconducting below 9.0, 4.3, and 0.3 K, respectively. Spectroscopic properties of the predicted phases are presented to aid in their eventual characterization, should they ever be synthesized.

“…For example, Gerhard Ertl commented on Fritz Haber's famous synthesis of ammonia from the elements, [1] Wolfgang A Herrmann on Ernst Otto Fischer's and Erwin Weiss' crystal structure determination of dibenzene chromium, [2] and Gary Schrobilgen on Rudolf Hoppe's synthesis of xenon difluoride. [3] The appreciation by the readership for this singular format became apparent immediately from the extraordinarily high numbers of full-text downloads. Leading in the latter respect is the contribution by Florian Kraus on Otto Ruff's early report on uranium hexafluoride, which later became a corner stone of uranium based nuclear technology.…”

“…Remarkable new chemistry has been presented Ϫ amongst others Ϫ by the research groups of Michael Ruck in synthesizing superconducting ferromagnetic Bi 3 Ni nanofibers, [6] Mathias Wickleder, who discovered a new class of sulfato complexes of the group 14 elements, [7] or of Wolfgang Schnick, presenting an unprecedented connectivity in nitridosilicate chemistry. [8] Particularly worth reading are John Goodenough's "Reflections on Sixty Years of Solid State Chemistry" [9] or Gérard Férey's exciting review on "Swelling Hybrid Solids".…”
