Organosoluble tetravalent actinide di- and trifluorides

Soluble molecular actinide(IV) fluorides can be prepared in high yield via redox or metathesis reactions of silver fluorides with actinide compounds containing ancillary iodide or fluorinated thiolate ligands. Two compounds, (py)4UF2I2·2py and (py)7Th2F5(SC6F5)3·2py were isolated and characterized by conventional methods, powder and low temperature single crystal X-ray diffraction.
