文摘

Hydrated cerium(IV) fluoride dissolves in hot dimethylsulfoxide to form yellow [CeF₄(Me₂SO)₂], the X-ray structure of which reveals a chain polymer with eight-coordinate cerium bound to two terminal and four bridging fluorines and two O-bonded Me₂SO molecules. The complex was also characterised by IR, ¹H and ¹⁹F{¹H} NMR and UV/visible spectroscopies. Attempts to use [CeF₄(Me₂SO)₂] as a synthon to prepare other complexes with phosphine oxides or 2,2鈥?bipyridyl were unsuccessful. Thorium(IV) fluoride hydrate does not react with boiling dmso.
