Notizen: 119Hg NMR chemical shifts of the stable mercury species HgCln2 - n with n = 0-4 were determined by a least-squares algorithm from 199Hg chemical shifts measured in 50 mM aqueous mercury solution as a function of the chlorine concentration at 25°C. The concentrations of the corresponding mercury species in the solutions necessary in this special procedures were calculated by using published equilibrium constants. The results relative to dimethyl-mercury are -2256 ppm (Hg2+), -1897 ppm (HgCl+), -1560 ppm (HgCl2), -1436 ppm (HgCl3-) and -1152 ppm (HgCl42-) with maximum errors of ±5 ppm.
