Synthesis and characterization of cobalt(II) and some nickel(II) complexes with N,N′-ethylenebis(p-X-benzoylacetone iminato) and N,N′-ethylenebis(p-X-benzoylmonothioacetone iminato) ligands

A series of tetradentate thio imine ligands, N,N′-ethylenebis(p-X-benzoylmonothioacetone imine), where X = H, CH3, CH3O, Br, and Cl, have been prepared from the corresponding tetradentate keto amines via nucleophilic substitution with bisulfide ion. Cobalt(II) complexes with all ligands have been prepared and characterized and are of particular interest because of their ability to combine reversibly with molecular oxygen in nonaqueous solutions at low temperatures. The new ligands and complexes have been characterized by elemental analyses and IR, NMR, and visible spectral data. A few of the corresponding Ni(II) complexes have also been prepared to aid in characterization via NMR techniques when the free ligands proved too insoluble for study.
