Popis: Mononuclear triple-stranded helicate complexes ML3 (M = Sc3+, La3+, Sm3+, Yb3+) were self-assembled and structurally characterized by NMR spectroscopy and high-resolution mass spectrometry. The solid-state structure of the ytterbium complex was determined by X-ray crystallography. The core lanthanide metal ion was replaced quantitatively by three sodium ions. Homo- and heterotrinuclear complexes containing the alkali metal ions Li+ and Na+ were obtained from the mononuclear lanthanide complexes. (© Wiley-VCH Verlag GmbH & Co.
