The reaction of [RuX3 (AsPh3) 3] and N, N-disubstituted pyridazine-3, 6-diamine in benzene under reflux afford novel binuclear, halo-bridged, ruthenium (III) complexes with the general formula [Ru2 (AsPh3) 2 (μ-X) 2X4 (L)](X= Cl or Br; L= N, N-disubstituted pyridazine-3, 6- diamine). All the complexes have been characterized by elemental analysis, spectral (UV– Vis, EPR) and electrochemical methods (CV, DPV). The electronic spectra of the ...
