| Abstract: | Six dimeric copper(II) complexes of the type Na[Cu2(D)(L)], where D = glycylglycinate dianion, and HL = imidazole and 2-methylimidazole; D = glycyl-L-tyrosinate dianion, HL = imidazole and benzimidazole; D = glycyl-L-phenylalaninate dianion, and HL = imidazole; and D = glycyl-L-tryptophenate dianion, and HL = benzimidazole, have been prepared. They were characterized by IR, visible absorption, and EPR spectroscopy. The EPR data indicated their complete dimeric behaviour in basic solution with two Cu(II) ions in close proximity of <7Å with imidazolate, 2-methyl-imidazolate, and benzimidazolate bridges. |
