Metal Complexes of 1, 10-phenanthroline Derivatives. XIV Complexes of 1, 10-phenanthrolin-2-yl-(pyridin-2-yl)amine
1, 10-Phenanthrolin-2-yl(pyridin-2-yl)amine has been prepared in low yield from 2-chloro-1, 10-phenanthroline and pyridin-2-amine. The molecule coordinates as a tridentate chelating agent of the ter-imine type and produces low-spin complexes with iron(ii) in both its neutral and anionic forms. The bis(1igand) cobalt(ii) complex is high-spin. Although the ligand provides a slightly weaker field than terpyridine, electronic and Mössbauer spectral data indicate a less distorted metal ion environment in its complexes, compared with those of terpyridine. This is correlated with the presence of the six-membered chelate ring.
