Structure of tetrakis(cyclopentadienyl)uranium(IV) acetate dioxide
Acetate ions can function as both monodentate and bidentate ligands but the crystallochemical factors which favour one of these two coordinations are not known. The title compound is a product obtained while attempting to synthesise tris(cyclopentadienyl)uranium acetate. Within the large series of cyclopentadienyl complexes of uranium(IV), the title compound is the first observed where the uranium(IV) exhibits a coordination number of seven. The bridging between U atoms occurs through acetate and oxide O atoms. The cyclopentadienyl ligands occupy the apical coordination sites of the bipyramids. The characterisation and structure analysis of this compound by single crystal X-ray diffraction are reported.
