2-Carboxy-9-dihydroxymethyl-1,10-phenanthroline Complexes of Cobalt(II) and Copper(II)

Bis(9-dihydroxymethyl-1,10-phenanthroline-2-carboxylato-N,N',O)cobalt(II) hydrate, [Co(C₁₄H₉N₂O₄)₂].H₂O, and bis(9-dihydroxymethyl-1,10-phenanthroline-2-carboxylato-N,N',O)copper(II) hydrate, [Cu(C₁₄H₉N₂O₄)₂].H₂O, are isostructural. The stable gem-diol ligands are tridentate (two N atoms and one carboxylate O atom) and form a distorted octahedron around the metal center. The total bite angle of the ligand is approximately 150°.
