    Protonated derivatives are isolable, e.g., [C 5 H 5 NOH]Cl. [3] Further demonstrating its (feeble) basicity, pyridine-N-oxide also serves as a ligand in coordination chemistry. A host of transition metal complexes of pyridine-N-oxides are known. Treatment of the pyridine-N-oxide with phosphorus oxychloride gives 4- and 2-chloropyridines. [8]
