摘要
The compound TlMe2(DABRd) (HDABRd = p-dimethylaminobenzyl-idenerhodanine) has been prepared and its crystal structure solved by X-ray diffraction analysis. The thallium atom is coordinated to the two methyl groups and to one nitrogen and one oxygen from the rhodanine moieties of two different deprotonated ligands. Weak Tl ... S interactions are also observed. Significant structural differences from TlMe2(Rd) (HRd = rhodanine) and spectroscopic (IR) characteristics in the solid state are discussed. H-1 and C-13 NMR studies and conductometric measurements indicate that in dimethylsulphoxide the compound is significantly ionized.
