Synthesis and Characterization by 19F and 125Te NMR and Raman Spectroscopy of cis-ReO2(OTeF5)3 and cis-ReO2(OTeF5)4 -, and X-ray Crystal Structure of [N(CH3)4 +][cis-ReO2(OTeF5)4 -] †

The pentafluorooxotellurate compound ReO(2)(OTeF(5))(3) has been synthesized from the reaction of ReO(2)F(3) with B(OTeF(5))(3) and structurally characterized in solution by (19)F and (125)Te NMR spectroscopy and in the solid state by Raman spectroscopy. The NMR and vibrational spectroscopic findings are consistent with a trigonal bipyramidal arrangement in which the oxygen atoms and an OTeF(5) group occupy the equatorial plane. The (19)F and …
