摘要:
Complexes formed by the dianions LH2- and L'2- deriving from dihydrolipoic acid (LH3) and dihydrolipoamide (L'H2), respectively, by substitution of the hydrogen atoms of the thiol groups with Ni(II), Co(II), Hg(II) and Cu(I) ions were synthesized, isolated and characterized. In all these compounds the metal ions are coordinated to the thiolic sulfur atoms of the ligands. Potentiometric and spectroscopic data (IR, UV-Vis, EPR and XPS) obtained for these complexes or for their solutions are discussed.
