  Synthesis, characterization of mono- and binuclear ruthenium(II) complexes with the potential O and S donor ligand 1,1′,2,2′- ethanetetra(thioglycolic acid) and their reactivity with π-acidic ligands

  摘要：

  Synthesis of mono- and binuclear Ru(II) complexes of the composition [RuL(H2O)] (1) and [Ru2L(H2O)2] (2), where L = 1, 1',2,2'-ethanetetra(thioglycolic acid), are reported. The interactions of 1 and 2 with the pi-acidic ligands such as CO, PPh3 and NO+ form octahedral species. The complexes were characterized by elemental analysis, IR, UV-vis, 1[H], C-13{H-1} and P-31{H-1} NMR spectroscopy, conductance measurements and differential pulse voltammograms. The redox potential, ruthenium(II)/ruthenium(I), of the complexes become more positive with an increase in the pi-acidity of the ligand coordinated to the metal ion.
