Argon is an extremely chemically inert element. HArF is presently the only experimentally known neutral molecule containing a chemically bound argon atom. Ab initio calculations at the MP2 and CCSD(T) levels presented here suggest, however, the existence of whole families of additional molecules. Explicitly predicted are FArCCH, with an argon–carbon bond, and FArSiF3, with an argon–silicon bond. These metastable compounds are found to be protected from decomposition by relatively high energy…

Predicted organic compounds derived from rare gas atoms and formic acid.

Results indicate that HCOOXeH and HCOOKrH are potential candidates for experimental observation and the formation mechanism of molecular orbitals is presented.

Stable Lithium Argon compounds under high pressure

A detailed analysis of the electronic structure of LiAr and Li3Ar shows that Ar in these compounds attracts electrons and thus behaves as an oxidizing agent, markedly different from the hitherto established chemical reactivity of Ar.

Reactivity of He with ionic compounds under high pressure

The authors demonstrate the driving force for helium reactivity, showing that it can form new compounds under pressure without forming any local chemical bonds.

Ab initio study of the organic xenon insertion compound into ethylene and ethane.

Natural bond orbital (NBO) analysis shows a strong ionic bond between the xenon atom and hydrocarbon radical and the interaction between the donor and acceptor increases the stability of HXeC2H3.

The present work demonstrated that the noble metal-noble gas interaction strength in MNgF species (with M=Cu and Ag, and Ng=Kr and Xe) is much stronger than that in NgMF systems, indicating strongest M-Ng interaction.

Charge distributions and bonding analysis indicate that HNgOSi(+) ions can be best represented as strong complexes between the [HNg](+) ions and OSi molecule.

Predicted organic noble-gas hydrides derived from acrylic acid.

This study predicts the existence of Kr- and Xe-derivatives of acrylic acid and the instability of Ar-related compounds.



A stable argon compound

It is reported that the photolysis of hydrogen fluoride in a solid argon matrix leads to the formation of argon fluorohydride (HArF), which is identified by probing the shift in the position of vibrational bands on isotopic substitution using infrared spectroscopy and indicates that HArF is intrinsically stable, owing to significant ionic and covalent contributions to its bonding.

New Rare-Gas-Containing Neutral Molecules

The synthesis of novel neutral rare-gas-containing molecules of type HXY, where × = Xe or Kr and Y is an electronegative atom or fragment, is discussed. The molecules are characterised experimentally

Combined FTIR and EPR studies of acetylene irradiated with fast electrons in a solid xenon matrix provide experimental evidence for the formation of HXeCCH, a novel-type organic molecule with an

Lifetime and decomposition pathways of a chemically bound helium compound

HHeF, a first predicted chemically-bound helium compound, is a metastable species that disintegrates by tunneling through energy barriers into He+HF and H+He+F. The reaction paths for these

Ab initio calculations at the B3LYP and MP4(SDQ) levels of theory were performed on the noble gas-containing compound H–Ar–Cl. The calculations indicate that the molecule should be metastable with an

Stability of a chemically bound helium compound in high-pressure solid helium

HHeF, a chemically-bound helium compound, has been predicted to be metastable in the gas phase. It decays by tunneling through energy barriers in picosecond timescales into He+HF and H+He+F. This
