Enhancement of the coordinating flexibility in a Schiff–Mannich combo ligand: forced generation of a new NiII–Ophenoxo–LnIII–Oalkoxo–LnIII array (Ln = Gd, Tb, Dy and Ho)

Abstract

A series of 3d–4f complexes, containing rare NiLn₂O₄ topology, were synthesized by designing a new type of combo Schiff base–Mannich ligand.
