Ternary Metal Complexes

Five new ternary metal complexes containing imidazole and glycylglycine or amino acid have been prepared and characterized by proton magnetic resonance and infrared spectral studies. Seven new binary metal complexes have also been prepared and studied. The isolation of Cd(imidazole)6Cl2•H2O and Ni(imidazole)6-Cl2•4H2O provides evidence that the coordination number of these metal ions to imidazole in the solid state is six. The visible spectra of the Ni(II) complexes of amino acid and imidazole show that all these are octahedral in aqueous solution.

A series of novel 1,9-diazodipyrrins (4) were readily synthesized by reacting aryldiazonium salts with 5-aryldipyrromethanes under both acidic and basic conditions. The zinc complex of 1,9-diphenylazodipyrrin (5aZn) was confirmed by X-ray crystallographic analysis, and 1,9-diazodipyrrins and their zinc and nickel complexes (5M) were characterized by 1H and 13C NMR, IR, UV–vis, and MS. All of the metal complexes absorb almost all colours of the rainbow; the absorption maximums are >650 nm and the half-band widths are over 100 nm. The fluorescence of the zinc complexes of 1,9-diphenylazodipyrrin (5aZn) and 1,9-di(2-iodophenylazo)dipyrrin (5cZn) were also explored.
