Synthesis and Characterization of New Ruthenium Complexes with 11-Carboxy-dipyrido (3,2-A:2’,3’-C)phenazine As Ligand

A general method for the synthesis of Ruthenium(II) complexes of the type [(HOOC-dppz)(2)RuX2] and [(HOOC-dppz)RuL2] (PF6)(2) (X = Cl- or SCN, L = 2,2'-dipyridine or 4,4'-dimethyl-2,2'-dipyridine and HOOC-dppz = 11-carboxy-dipyrido(3,2-a:2',3'-c)phenazine) is reported. The complexes were characterized by conventional technics as UV-Visible, IR and H-1-NMR spectroscopies and cyclic voltammetry.
