“…Noble gas chemistry has a relatively short history since 1962, − but it has been becoming a fascinating new field for experimental and theoretical study in recent years. − Many new types of noble-gas-containing molecules or ions have been experimentally observed or theoretically predicted. For example, a large variety of HNgY (Ng = noble gas atom, Y = electronegative atoms or groups) type molecules, − FNgCCH, and FNgCN , have been made by Räsänen, Khriachtchev, and co-workers, noble-gas-coordinated transition-metal complexes such as M(CO) 5 Ng have been studied by Perutz and Turner, (η 5 -C 5 R 5 )M(CO) 2 Ng have been observed by George and co-workers, AuXe 4 2+ (Sb 2 F 11 – ) 2 have been isolated by Seidel and Seppelt − and modeled by Hu and Huang, the noble-gas-complexed actinide compounds CUO·Ng x have been obtained by Andrews − and co-workers, the noble gas noble metal halide complex (NgMX) has been observed by Gerry − and co-workers, the FNgBO, FNgBNR, F – (NgO) n , NNgO 3 – , and FNgCC – have been predicted by Hu ...…”
