Abstract

Mercury(II) complexes of imidazolidine-2-thione and its derivatives have been synthesized and their ¹H, ¹³C and ¹⁹⁹Hg NMR spectra measured. HgCl₂ forms L₂HgCl₂ type complexes (where L = imidazolidine- 2-thione and its derivatives). The NH group of the ligand is shifted downfield by about +1.37 ppm in the ¹H NMR after complexation. The C-2 carbon in the ¹³C NMR is shifted by −6.50 ppm for mono N-substituted ligands, but by −5.30ppm for N,N'-disubstituted ligands. The ¹⁹⁹Hg NMR resonance is shifted by about −60 ppm for N-substituted ligands, but −140 ppm shifts were observed for N, N'-disubstituted ligands.
