Abstract: | We report the synthesis and structural characterization of UO(2)(ReO(4))(DPPMO(2))(2)]ReO(4)] and UO(2)(Cl)(DPPMO(2))(2)]Cl] (where DPPMO(2) = bis(diphenylphosphino)methane dioxide). In both complexes, the linear uranyl dication is coordinated to two bidentate DPPMO(2) ligands in the equatorial plane with one coordinated and one non-coordinated anion (either perrhenate or chloride). We have also prepared the pertechnetate analogue, and, through (31)P and (99)Tc NMR, we have shown that the cation, UO(2)(TcO(4))(DPPMO(2))(2)](+), is stable in solution. |
