“…These deviations from 90°w ere not considered to be significant. It was identified by mass analysis in a time-of-flight mass spectrometer (70). In general, higher yields are obtained by using barium perxenate, Ba2Xe03, rather than the more finely divided sodium salt (139).…”

“…The small noble gas molecules or ions discovered or predicted so far can, based on the bonding on the noble gas atom, be roughly categorized into two types: the ''donor-acceptor type'' complexes such as NgBeO, 41 NgMX, M(NBeHe)n, and the ''covalent type'' noble gas molecules such as HNgF, [3][4][5] HNgCCH, 7,8 FNgCCH, FNgBO, XeF 2 , 42 XeO 4 , 43,44 FNgO À , FNgBN À , NXeO 3 À , and FNgCC À . The ''donor-acceptor type'' complexes can be thought of as formed by donating a lone pair of electrons of the noble gas atom to the neighboring metal atom or electron deficient groups.…”

We have computationally predicted a new class of stable noble-gas molecules FNgBNR (Ng = Ar, Kr, Xe; R = H, CH3, CCH, CHCH2, F, and OH). The FNgBNR were found to have compact structures with F-Ng bond lengths of 1.9-2.2 Å and Ng-B bond lengths of ~1.8 Å. The endoergic three-body dissociation energies of FNgBNH to F + Ng + BNH were calculated to be 12.8, 31.7, and 63.9 kcal mol(-1), for Ng = Ar, Kr, and Xe, respectively at the CCSD(T)/CBS level. The energy barriers of the exoergic two-body dissociation to Ng + FBNH were calculated to be 16.1, 24.0, and 33.2 kcal mol(-1) for Ng = Ar, Kr, and Xe, respectively. Our results showed that the dissociation energetics is relatively insensitive to the identities of the terminal R groups. The current study suggested that a wide variety of noble-gas containing molecules with different types of R groups can be thermally stable at low temperature, and the number of potentially stable noble-gas containing molecules would thus increase very significantly. It is expected some of the FNgBNR molecules could be identified in future experiments under cryogenic conditions in noble-gas matrices or in the gas phase.

“…However, since the first experimentally proved synthesis of the metal-based NG compound by Bartlett 1 , many other NG compounds were found to exist [2][3][4][5][6] . Specifically, most of the early NG compounds were synthesized by oxidizing the nobel gas elements with the highly electronegative elements such as fluorine [7][8] and oxygen [9][10][11][12] . Yet later, it was also found that the high-pressure compression constitutes another suitable and promising route for the synthesis of NG compounds.…”

“…The noble gas (NG) elements (e.g., He, Ne, Ar, Kr, and Xe) are historically known as inert elements due to their low level of reactivity arising from the completely filled outermost electron shells (the closed subshell configuration).

In general, as an important tool to synthesize new compounds, pressure can dramatically alters the lattice and electronic structure of condensed matter systems, as well as stimulates new phenomena that cannot be observed at ambient conditions.…”

The metal-based noble gas compounds exhibit interesting behavior of electronic valence states under pressure. For example, Xe upon compression can gain electrons from the alkali metal, or lose electrons unexpectedly to Fe and Ni, toward formation of stable metal compounds. In addition, the Na 2 He is not even stabilized by the local chemical bonds but via the long-range Coulomb interactions. Herein, by using the first-principles calculations and the unbiased structure searching techniques, we uncover that the transition metal Y is able to react with Xe above 60 GPa within various Y-Xe stochiometries, namely the YXe, YXe 2 , YXe 3 and Y 3 Xe structures. Surprisingly, it is found that all the resulting compounds are intermetallic and Xe atoms are positively charged. We also argue that the pressure-induced changes of the energy orbital filling are responsible for the electron transfer from Xe to Y.Meanwhile, the Peierls-like mechanism is found to stabilize the energetically most favorable YXe-Pbam phase. Furthermore, the predicted YXe-Pbam, YXe-Pnnm, and YXe 3 -I4/mcm phases are discovered to be a phonon-mediated superconductors under pressure, with the critical superconducting temperatures in the range of approximately ** Corresponding author email: puchunying@126.com 3-4K, 7-10K, and 5-6K, respectively. In summary, our work promotes further understanding of the crystal structures and electronic properties of the metal-based noble gas compounds. compounds were synthesized by oxidizing the nobel gas elements with the highly electronegative elements such as fluorine 7-8 and oxygen 9-12 . Yet later, it was also found that the high-pressure compression constitutes another suitable and promising route for the synthesis of NG compounds. For example, the compression of noble gases and some molecular species leads to the formation of multiple van der Waals solids at relatively low pressure, such as: HeN 4 13 , He-H 2 O 14 , Ar(H 2 ) 2 15 , ArO 2 , Ar(O 2 ) 16 , Kr(H 2 ) 4 17 , Xe(H 2 ) 8 18 , Xe-N 2 19 , Xe-CH 4 20 , Xe-H 2 O 21 and Xe(O 2 ) 2 16 .
