Solution behaviour in DMSO using 1D and 2D NMR spectroscopy was performed for lanthanide complexes Ln(L)(HL) and Ln(HL) 2 Cl, containing non-macrocyclic 2-(tosylamino)-benzylidene- N -benzoylhydrazone (H 2 L), and the structure of [Yb(L)] + cation in solution was determined. Based on the NMR data, t...
