Methylmercury(II) derivatives of Pyridine-2(1H)-thione

Abstract

Methylmercuric nitrate reacts with pyridine-2(lH)-thione (C₅H₅NS) in acetone to give methyl-(pyridine-2(1H)-thione)mercury(11) nitrate, [MeHg(C₅H₅NS)] NO₃. This complex reacts with sodium bicarbonate in acetone to give methyl(pyridine-2-thiolato)mercury(11), MeHg(C₅H₄NS).Infrared, Raman, and nuclear magnetic resonance spectra indicate that MeHgH is bonded to sulphur in both complexes, and that protonation of nitrogen occurs on reaction of MeHg(CsH,NS) with nitric acid to give [MeHg(C₅H₅NS)] NO₃.
