水合氟化铈（IV）溶于热的二甲基亚砜中形成黄色的[CeF 4（Me 2SO）2]，其X射线结构显示为一个链状聚合物，其中8个配位的铈与两个末端和4个桥连的氟和两个O-键合的Me 2SO分子结合。配合物的结构经IR、~ 1H和~（19）F {~ 1H} NMR和UV/可见光谱表征。尝试使用[CeF 4（Me 2SO）2]作为合成子来制备与氧化膦或2，2 ′-联吡啶的其他配合物是不成功的。氟化钍（IV）水合物不与沸腾的DMSO反应。
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 and19F{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′-bipyridyl were unsuccessful. Thorium(IV) fluoride hydrate does not react with boiling dmso.
