摘要:
The complexes trans-[Ru(L-L)2X2] [X = Cl, Br or I; L-L = bidentate ligand including PhSe(CH2)2SePh, MeSe(CH2)2SeMe and o-C6H4(TeMe)2] have been prepared by reaction of RuCl3 . xH2O and LiX with the ligand in alcoholic solvents in the presence of a reducing agent. The complexes have been characterized by analysis, IR, UV-vis and Se-77 or Te-125 NMR spectroscopies and the Ru(II)-Ru(III) redox potentials established by cyclic voltammetry. The crystal structure of trans-[Ru{PhSe(CH2)2SePh}2Cl2] has been determined, giving Ru-Cl 2.413(1), 2.444(1), Ru-Se 2.433(1)-2.460(1) angstrom.
