Ruthenium(III); Schiff base ligand; triphenylphosphine; triphenylarsine; catalytic oxidation.

Six different ruthenium(III) complexes of Schiff bases derived from 2-hydroxy-1-naphthaldehyde and 𝑜-aminophenol/𝑜-aminothiophenol have been synthesized. The compounds with the general formula [RuX(EPh₃)₂(L)] (X = Cl or Br; E = P or As; L = bifunctional tridentate ONO/ONS donor Schiff base ligand) were characterized by infrared, electronic, electron paramagnetic resonance spectroscopy and elemental analyses. Spectroscopic investigation reveals coordination of Schiff base ligand through ONO/ONS donor atoms and octahedral geometry around ruthenium metal. Redox property of complexes has been examined by using cyclic voltammetry. The catalytic oxidation property of ruthenium(III) complexes were also investigated.
