Nitrogen-Rich Azoles as Ligand Spacers in Coordination Polymers

Abstract

N-heterocycle-based ligands are versatile building-blocks for coordination oligomer and polymer assemblies of first-row transition metals. Herein, we review recent developments in the design and synthesis of some nitrogen-rich azole-based ligands, their assembly modes in coordination oligomers and polymers, and the potential applications of the resulting metallosupramolecules.
