摘要：

Hexakis(dimethyl sulphoxide)mercury(II) trifluoromethanesulphonate, [Hg(dmso)(6)](O3SCF3)(2), is a stable, readily synthesized compound which is an excellent standard for setting up CP/MAS experiments in solid-state Hg-199 NMR. The isotropic chemical shift, delta(iso) -2313 ppm, is to lower frequency than that measured for the same material in solution. The static spectrum exhibits of powder pattern indicative of axial symmetry about the mercury atom, with a chemical shift anisotropy of 122 ppm.
