Synthesis and characterization of phenyl[5-(2-pyridinylmethylene)-2-thiohydantoinato]mercury(II), and the crystal and molecular structures of its DMSO solvate

Reaction of phenylmercury(II) acetate with HPyTd (HPyTd = (5-(2-pyridinylme thylene)-2-thiohydantoin) yields [HgPh(PyTd)]. The complex has been charact erized by elemental analysis and IR and NMR (H-1, C-13 and Hg-199) spectros copy. The crystal structure of [HgPh(PyTd)].DMSO has been established by X- ray analysis. The mercury atom is coordinated to a phenyl carbon, the thioh ydantoin N(1) and the pyridine N in a T-shaped arrangement and is additiona lly involved in weak Hg ...
