Synthesis of novel salts with HF, AsF3 and XeF2 as ligands to metal cations

XeF4 as a Ligand for a Metal Ion

“…[5] The first coordination compound with a noble-gas fluoride acting as a ligand to a metal ion was [Ag(XeF 2 ) 2 ]AsF 6 . [6] A series of such coordination compounds has since been prepared, [7] but coordination compounds with XeF 4 , (a poorer Lewis base or less thermally stable than XeF 2 [8] ) as a metal ion ligand, were not known.…”

Syntheses, structures and Raman spectra of Cd(BF4)(AF6) (A=Ta, Bi) compounds

“…To enable the coordination with weak fluoroligands like HF [1], AsF 3 [2], XeF 2 [3] and XeF 4 [4], the metal center needs to be practically naked. This is facilitated by the use of weakly coordinating fluoroanions [5,6], such as PF 6 À , AsF 6 À and SbF 6 À .…”

A Raman spectroscopic study of the XeOF4/XeF2 system and the X-ray crystal structure of α-XeOF4·XeF2

“…A considerable number of metal cations exhibiting this behavior towards XeF 2 have been synthesized and structurally characterized. Recent reviews outlining progress in this area [9,10] [20], Xe [21]) have been reported which contain NgF 2 molecules that are terminally coordinated to bromine(V) through fluorine. The Ng-F stretching frequencies of main-group cation complexes with NgF 2 show frequency shift patterns that are similar to those of the metal cation complexes (vide supra).…”
