The electrochemistry of HgCl2 and [Hg(NTf2)2] ([NTf2]鈭?/sup> = bis{(trifluoromethyl)sulfonyl}imide) has been studied in room temperature ionic liquids. It has been found that the cyclic voltammetry of Hg(II) is strongly dependent on a number of factors (e.g., concentration, anions present in the mixture, and nature of the working electrode) and differs from that found in other media. Depending on conditions, the cyclic voltammetry of Hg(II) can give rise to one, two, or four reduction peaks, whereas the reverse oxidative scans show two to four peaks. Diffuse reflectance UV鈭抳is spectroscopy and X-ray powder diffraction have been used to aid the assignment of the voltammetric waves.
