The reaction of phenylmercury(II) chloride with acetophenonethiosemicarbazone (Hatsc) in ethanol in 1:1 mole ratio undergoes symmetrisation forming the products, HgCl2(Hatsc)2 and Ph2Hg instead of the anticipated compound PhHgCl(Hatsc). The analytical data, some physical properties, IR and NMR (1H, 13C, 199Hg) spectroscopy all support the formation of HgCl2(Hatsc)2. 199Hg NMR of the solid obtained from the filtrate of the reaction provides evidence for Ph2Hg. This reaction represents the first example of a symmetrisation phenomenon observed in organomercury(II)-thiosemicarbazone chemistry.
