Methylmercury and dimethylthallium complexes of 5-(4′-dimethylaminobenzylidene)-2-thiohydantoin (HDABTd)

摘要: Abstract The ligand 5-(4′-dimethylaminobenzylidene)-2-thiohydantoin (HDABTd) was prepared and its structure determined by X-ray diffraction. In the crystal, molecules are linked in chains along [110] direction intermolecular N(3)–H(3)⋯O(1)I N(1)–H(1)⋯Sii hydrogen bonds. complexes [HgMe(DABTd)] [TlMe2(DABTd)] were reaction of with methylmercury acetate or dimethylthallium hydroxide, characterized solid state IR spectroscopy solution conductivity measurements 1H, 13C, 199Hg 205Tl NMR spectroscopy. complex crystallized DMSO as [TlMe2(DABTd)(DMSO)], an diffraction study which showed thallium atoms to be coordinated two methyl C atoms, oxygen atom a molecule, S N(1) one DABTd and, more weakly, neighbouring DABTd. This last interaction links parallel b axis. Crystals methylmercury(II) contain three [HgMe(DABTd)]·DMSO structures per asymmetric unit, but poor data quality prevented complete refinement.
