Application

Pyridine (py) may be used in the preparation of vanadium oxide nanoparticles and iron benzenedicarboxylates, Fe(OH)(BDC)(py)0.85 (BDC = 1,4-benzenedicarboxylate, py = pyridine). It may be employed as catalyst in Knoevenagel condensation reaction.

General description

Pyridine is a basic N-heterocyclic compound. It acts as nitrogen donor ligand and forms many metal-pyridine complexes. Its complexes having tetrahedral and octahedral geometries can be differentiated by infra-red spectral investigations.
