Synthesis and characterizartion of dinuclear ruthenium(II) complexes with dianion of 2,5-dihydroxy-1,4-benzoquinone as bridging ligand

摘要

The ruthenium complexes of the type [{(phen)-2Ru}_2(#mu#-L)](ClO_4)_2, [{(py)_4Ru}_2(#mu#-L)](ClO_4)_2, [{(PPh_3)_3Ru}_2(#mu#-L)](ClO_4)_2 and [{(Me_2SO)_3Ru}_2(#mu#-L)](Cl)_2 (where phen = 1,10-phenanthroline, py = pyridine, PPh_3 = triphenylphosphine, Me_2SO = dimethyl-sulphoxide ad L = dianion of 2,5-dihydroxy-1,4-benzoquinone) have been synthesised and characterized by elemental analysis, IR, NMR and voltammetric studies.
