Abstract

The first example of a uranyl selenocyanate compound is reported. The compound[Et4N]3[UO2(NCSe)5] has been synthesized and fully characterized by vibrational and multinuclear(1H,13C{1H} and77Se{1H}) NMR spectroscopy. The photophysical properties have also been recordedand trends in a series of uranyl pseudohalides discussed. Spectroscopic evidence shows that theU–NCSe bonding is principally ionic. An electrochemical study revealed that the reduced uranyl(V)species is unstable to disproportionation and a ligand based oxidation is also observed. The structureof [Et4N]4[UO2(NCSe)5][NCSe] is also presented and Se ̈ ̈ ̈H–C hydrogen bonding and Se ̈ ̈ ̈Sechalcogen–chalcogen interactions are seen.
