Photolysis of Re((PrCP)-Pr-i)(CO)(2)(PF3) in liquid or supercritical Xe yields two new compounds [Re((PrCp)-Pr-i)(CO)(2)Xe and Re((PrCp)-Pr-i)(CO)(PF3)Xe]. Re((PrCp)-Pr-i)(CO)(PF3)Xe has been characterized by NMR and IR spectroscopies. The compound is an organometallic Xe complex that has been characterized by using NMR spectroscopy and is shown to be longer-lived than other organometallic Xe complexes by IR spectroscopy. F-19, P-31, and Xe-129 chemical shifts have been determined. The Xe-129 chemical shift of Re((PrCp)-Pr-i)(CO)(PF3)Xe, delta -6,179, is a Xe shift that is significantly shielded, on the order of 1,000 ppm, with respect to free Xe. The coupling constants between coordinated Xe-129 and both the F-19 and P-31 nuclei present have been Extracted, confirming the identity of the compound. Observed line widths give a lower limit to the lifetime of the coordinated Xe of 27 ms at 163 K.
