Preparation of diorganothallium (III) complexes with an "N6" macrocyclic ligand and their 1H and 13C NMR spectra.
Diorganothallium(III) complexes with an ‘N6’ macrocyclic ligand were prepared by using Schiff base condensation of 2,6-diacetylpyridine with ethylenediamine. 13C NMR signals of the ligand carbons were split by spin–spin coupling with the thallium nucleus. The dimethylthallium(III) complex shows the largest 1J(Tl-CH3) and 2J(Tl-CH3) values among dimethylthallium(III) compounds.
