Lanthanide contraction for helicity fine-tuning and helix-winding control of single-helical metal complexes

摘要

Lanthanide contraction was used for helicity fine-tuning and helix winding control of single-helical tetranuclear complexes LZn(3)Ln (Ln = La-Lu); heavier lanthanides formed a tighter helix with a higher M/P ratio and gave a more abundant partially-coiled structure, resulting in 14-step structural control of the helical complexes.
