Spectroscopic evidence for the direct coordination of the pertechnetate anion to the uranyl cation in [UO2(TcO4)(DPPMO 2)2]+

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
