Abstract

Methyl(dimethylsulfoxide)mercury(II) tetrafluoroborate has been prepared from methylmercury(II) tetrafluoroborate and dimethylsulfoxide (DMSO) in dichloromethane solution in high yield as a colourless crystalline solid. IR and NMR spectra suggest the presence of a solely O-bonded DMSO ligand at mercury. The crystal has been shown to have an ionic structure made up of MeHg(DMSO)⁺ cations and (disordered) BF₄^- anions by an X-ray diffraction study. The short HgO contact, 2.066(8) Å, and the values of the angles HgOS, 119.3(5)°, and CHgO, 178.7(5)°, are indicative of strong covalent DMSO coordination.
