HgF2 and Hg have been trapped in dilute F2/Ar and neat F2 matrices, subjected to UV-Vis and vac-UV photolysis and annealing, with the products identified by FTIR, UV-Vis-NIR and Hg L3-edge XAFS spectroscopic techniques. Whilst there was no convincing evidence for the formation of HgF4 under our argon matrix isolation conditions, a new Hg?F2 complex was identified and subsequent photolysis yielded HgF2 very cleanly. Hg L3-edge EXAFS has provided the first experimental value of 1.94(2) angstrom for the Hg-F bond length in HgF2, which is in excellent agreement with the computational values incorporating relativistic effects.
