Transition_metal_complexes_of_pyridine-N-oxides
Transition metal complexes of pyridine-N-oxides encompass coordination complexes that contain pyridine-N-oxides as ligands. Particularly common are the octahedral homoleptic complexes of the type [M(ONC5H5)6]2+ where M = Mn(II), Fe(II), Co(II), Ni(II).[2] Many variations of pyridine N-oxide are known, such as the dioxides of 2,2'- and 4,4'-2,2'-bipyridine.[3] Complexes derived from the trioxide of terpyridine have been crystallized as well.[4]
