Reactions between XeF2 or alkali metal tetrafluorohalogenates(III) and Rare Earth elements oxides, ZrO2, and HfO2 have been studied. The formation conditions of the binary and complex fluorides have been investigated. The comparison of the fluorination activity of Xe(II), Cl(III), and Br(III) fluorides has been proposed.

Single-crystalline tetrafluoridochlorates(III) A[ClF4] (A = K, Rb, Cs) were synthesized from solvolysis reactions of alkali metal fluorides in liquid chlorine trifluoride. The structures were examined by means of single-crystal X-ray diffraction. K[ClF4] crystallizes in the K[BrF4] structure type, whereas the Rb and Cs compounds crystallize in the Li[AuF4] structure type.

AbstractSingle crystal structures are presented for the IF2−, ClF4−, IF4−, TeF7−, and AsF4− fluoroanions. The 1,1,3,3,5,5 hexamethylpiperidinium (pip+) ion was used as cation in order to obtain good crystallinity and to avoid twinning and disorder which are notorious with the tetramethylammonium ion. Precise structural data are obtained for the first time, and the ions have the expected geometries. The pip+ has the further advantage that cation‐anion interactions are weak, which results in fairly ideal structures of the anions. Pip+BrF2− is too unstable to be obtained in single crystal form, and pip+BrOF4− as well as NO+BrOF4− show disordered anions and cations.
