The dependence of the Xe-129 NMR chemical shift value of XeF2 on temperature and concentration was determined in a variety of prototypic media: in acidic (anhydrous HF, aHF), nonprotic but polar (dichloromethane), and basic (CD3CN-EtCN, 1: 3 v/v) solvents. The Xe-129 NMR spectra of a representative series of organoxenon(II) salts [RXe][Y] (R=C6F5, heptafluoro-1,4-cyclohexadien-1-yl (cyclo-1,4-C6F7), pentafluoro-1,4-cyclohexadien-3-on-1-yl (cyclo-3-O-1,4-C6F5) CF2=C(CF3), (CF3)(2)CFC=C C4H9C=C; Y=BF4, AsF6) in aHF showed, compared with XeF2 -aHF, a quantitatively less distinct but qualitatively related dependence of delta(Xe-129) vs temperature. The dependence of their delta(Xe-129) values on concentration in aHF is negligible. An explanation for the different behavior of [RXe][Y] and XeF2 is offered.
