Mononuclear triple‐stranded helicate complexes ML 3 (M = Sc 3+ , La 3+ , Sm 3+ , Yb 3+ ) 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.
