Description

General description

Pyridine is a basic N-heterocyclic compound. It acts as a nitrogen donor ligand and forms many metal-pyridine complexes. It has wide applications as a solvent, catalyst, and intermediate for synthesis.

Application

• Ligand-Modulated Nuclearity and Geometry in Nickel(II) Hydrazone Complexes: From Mononuclear Complexes to Acetato- and/or Phenoxido-Bridged Clusters.: Research on the use of pyridine and its derivatives to control the nuclearity and coordination geometry in nickel(II) complexes, which is crucial for designing metal-organic frameworks and catalytic sites (Vrdoljak et al., 2023).


• Non-palindromic (C^C^D) gold(III) pincer complexes are not accessible by intramolecular oxidative addition of biphenylenes - an experimental and quantum chemical study.: A study examining the limitations of pyridine-containing ligands in stabilizing reactive gold(III) complexes, providing insights into the electronic properties and stability challenges (Feuerstein & Breher, 2021).
