Uses

Used in Organic Chemistry:
Mercury(II) fluoride is used as a selective fluorination agent for the synthesis of organic fluorine compounds. It plays a crucial role in the fluorination of organic compounds such as triphenylacetic acid, triphenyl ethylene, and triethyl phosphite in dimethylsulfoxide/HgF2 solutions under UV-visible illumination. This selective fluorination process allows for the introduction of fluorine atoms into organic molecules, which can significantly alter their chemical and physical properties.
Additionally, Mercury(II) fluoride has been utilized in the synthesis of CF2I2 by fluorination of tetraiodomethane. MERCURY(II) FLUORIDE is then purified, demonstrating the versatility of Mercury(II) fluoride in organic synthesis and its ability to produce a range of fluorinated compounds.

Noble-gas difluoride complexes of mercury(II): The syntheses and structures of Hg(OTeF5)2·1.5NgF2 (Ng = Xe, Kr) and Hg(OTeF5)2

The synthesis of high-purity Hg(OTeF5)2 has resulted in its structural characterization in the solid state by Raman spectroscopy and single-crystal X-ray diffraction (XRD) and in solution by 19F NMR spectroscopy. The crystal structure of Hg(OTeF5)2 (-173 C) consists of discrete Hg(OTeF5)2 units having gauche-conformations that interact through long Hg - -O and Hg - -F intramolecular contacts to give a chain structure. The Lewis acidity of Hg(OTeF5)2 toward NgF2 (Ng = Xe, Kr) was investigated in SO2ClF solvent and shown to form stable coordination complexes with NgF2 at -78 C. Both complexes were characterized by low-temperature Raman spectroscopy (-155 C) and single-crystal XRD. The complexes are isostructural and are formulated as Hg(OTeF5) 2·1.5NgF2. The Hg(OTeF5)2 units of Hg(OTeF5)2·1.5NgF2 also have gauche-conformations and are linked through bridging NgF2 molecules, also resulting in chain structures. These complexes represent the only examples of coordination compounds where NgF2 coordinates to mercury in a neutral covalent compound and the only example of mercury coordinated to KrF2. Moreover, the Hg(OTeF5)2·1. 5KrF2 complex is the only KrF2 complex known to contain a bridging KrF2 ligand. Energy-minimized gas-phase geometries and vibrational frequencies for the model compounds, [Hg(OTeF5) 2]3 and [Hg(OTeF5)2] 3·2NgF2, were obtained and provide good approximations of the local environments of Hg(OTeF5)2 and NgF2 in the crystal structures of Hg(OTeF5)2 and Hg(OTeF5)2·1.5NgF2. Assignments of the Raman spectra of Hg(OTeF5)2 and Hg(OTeF 5)2·1.5NgF2 are based on the calculated vibrational frequencies of the model compounds. Natural bond orbital analyses provided the associated bond orders, valencies, and natural population analysis charges.

One dimensional group 12 metal undecafluoridoditantalates

The reactions between group 12 metals and the acidic TaF5were studied in the anhydrous HF (aHF) solvent. We were able to prepare and characterize the first compounds containing metal M2+cations and undecafluoridodimetallate anions – M(Ta2F11)2(M?=?Cd, Hg) without the additional cations, anions or ligands included in the crystal structure. They both crystallize in P-1 space group with cell parameters a?=?9.1571(4)??, b?=?9.8750(3)??, c?=?10.9400(7) ?, α?=?94.389(4)°, β?=?113.124(5)°, γ?=?101.142(3)°, V?=?879.81(8) ?3, Z?=?2, T?=?150?K (Cd(Ta2F11)2) and a?=?9.1381(5)??, b?=?9.8613(6)??, c?=?11.4470(7)??, α?=?114.086(6)°, β?=?102.290(5)°, γ?=?100.398(5)°, V?=?877.84(11) ?3, Z?=?2, T?=?150?K (Hg(Ta2F11)2). Metal cations connected through two anions form chains along b axis.

Revealing the structural chemistry of the group 12 halide coordination compounds with 2,2′-bipyridine and 1,10-phenanthroline

The coordination compounds of group 12 halides with 2,2′-bipyridine (bpy) and 1,10-phenanthroline (phen), 2[CdF2(bpy)2]·7H2O (1), [ZnI(bpy)2]+·I3 ? (2), [CdI2(bpy)2] (3), [Cd(SiF6)H2O(phen)2]·[Cd(H2O)2(phen)2]2+·F–·0.5(SiF6)2–·9H2O (4), [Hg(phen)3]2+·(SiF6)2–·5H2O (5), [ZnBr2(phen)2] (6), 6[Zn(phen)3]2+·12Br–·26H2O (7) and [ZnI(phen)2]+·I– (8), have been synthesized and characterized by X-ray crystallography, IR spectroscopy, elemental and thermal analysis. Structural investigations revealed that metal : ligand stoichiometry in the inner coordination sphere is 1 : 2 or 1 : 3. A diversity of intra- and intermolecular interactions exists in structures of 1–8, including the rare halogen?halogen and halogen?π interactions. The thermal and spectroscopic properties were correlated with the molecular structures of 1–8. Structural review of all currently known coordination compounds of group 12 halides with bpy and phen is presented.

Contributions to the chemistry of brominetrifluoride. Part 2. Bis(pentafluorophenyl)bromonium cations with weak nucleophilic fluoroelementate anions

BrF3 reacts with MII(C6F5)2 (M = Zn, Cd, Hg) in organic solvents independent of the stoichiometry under formation of C6F5BrF2. Bromonium compounds [(C6F5)2Br]+ [EFn+l]- (E = Sb, As, B) are formed in equimolar reactions if additionally Lewis-acids EFn are present. [(C6F5)2Br]+ [BF4]- results in quantitative yield independent of the stoichiometry of substrates if BrF3 reacts with the Lewis-acidic aryl transfer reagent (C6F5)2BF. The molecular structure of the bromonium compounds [(C6F5)2Br]+ [BF4]- and [(C6F5)2Br]+ [AsF6]- can be interpreted in terms of two asymmetric hypervalent bonds at bromine(III). In solution the electrophilicity of Br(III) in [(C6F5)2Br]+ [EFn+l]- is responsible for the strong dependence of the 19F NMR shift values from the nucleophilicity of the solvent. Gauthier-Villars.
