Cover Picture: Spectroscopic Observation of a Group 12 Oxyfluoride: A Matrix-Isolation and Quantum-Chemical Investigation of Mercury Oxyfluorides (Angew. Chem. Int. Ed. 33/2012)
Mercury amalgam dental fillingsprovide a source for laser-ablated mercury atoms as reaction partners with OF2 to produce mercury difluoride and two major oxyfluorides, as shown by S. Riedel et al. in their Communication on page 8235 ff. Assignments for OHgF and FOHgF trapped in solid neon and argon in the IR spectrum were supported by calculations. Unpaired electron spin resides on oxygen in OHgF, with mercury in the +II oxidation state.
