XeF4 as a Ligand for a Metal Ion

Noble molecule: [Mg(XeF(2))(XeF(4))](AsF(6))(2) is the first coordination compound in which XeF(4) acts as a ligand to a metal center. It is also the first known compound, in which XeF(2) and XeF(4) are simultaneously coordinated to the same metal center (see structure; purple Xe, green F, gray Mg, yellow As).

A general method for the synthesis of polymeric binary flurides exemplified by AgF3, NiF4, RuF4, and OsF4

Fluride-ion capture from their anion relatives in anhydrous hydrogen fluoride solution by strong fluoride ion acceptors such as AsF5 provides a general approach to the synthesis of polymeric binary fluorides and is particularly advantageous in the synthesis of highest-oxidation-state transition metal polymeric fluorides.
