%X Complexes of the tridentate chelating agent 1,l0-phenanthroline-2- carboxamide, with bivalent iron, cobalt, nickel, and copper are described. Bis-ligand, six-coordinate complexes were obtained with all metals. A series of mono-ligand complexes, which are also believed to be six-coordinate, was also obtained. Infrared evidence indicates that the amide group is bound through the oxygen atom. Electronic spectral and magnetic data indicate that the ligand produces a relatively weak field and the iron complexes are high-spin. The tris-ligand iron(11) complex of pyridine-2-carboxamide is also described. This too is high-spin, although the bidentate amide apparently produces a slightly stronger field than the tridentate.
