Synthesis, Structure, and Bonding of a Xe(IV) Transition-Metal Coordination Complex, F3XeFb---WOF4.

The coordination complex, F3XeFb---WOF4, was synthesized in CFCl3 solvent by reaction of the weak fluoride-ion donor and strong oxidative fluorinating agent, XeF4, with the moderate-strength fluoride-ion acceptor, WOF4. The compound is the only transition-metal coordination complex of Xe(IV) and was characterized at low temperatures by single-crystal X-ray diffraction and Raman spectroscopy. Xenon tetrafluoride and WOF4 coordinate trans to the W=O bond through a W---Fb bond. The XeF3 moiety of F3XeFb---WOF4 acquires a degree of [XeF3]+ character upon coordination that is reflected by its stretching frequencies which are intermediate with respect to those of XeF4 and [XeF3]+. Calculations show W---Fb is predominantly an electrostatic, σ-hole bond with a significant orbital contribution that accounts for the bent Xe-Fb---W angle. The calculations show F3XeFb---MOF4 (M = Cr, Mo) are less stable than their W analogue, consistent with failed attempts to synthesize F3XeFb---MoOF4.
