Abstract

We report the synthesis and structural characterization of [UO ₂-(ReO₄)(DPPMO₂)₂][ReO₄] and [UO₂(CI)(DPPMO₂)₂][CI] (where DPPMO ₂ = bis(diphenylphosphino)methane dioxide). In both complexes, the linear uranyl dication is coordinated to two bidentate DPPMO₂ 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 ³¹P and ⁹⁹Tc NMR, we have shown that the cation, [UO₂(TcO₄)(DPPMO₂) ₂]⁺, is stable in solution.
