SYNTHESIS AND CHARACTERISATION OF RUTHENIUM(III)COMPLEXES CONTAINING MONOBASIC BIDENTATE SCHIFF BASES AND THEIR BIOLOGICAL ACTIVITIES

摘要

New hexa-coordinated ruthenium (III) complexes of the type [RuX_2(L)(EPh_3)_2] (X = Cl or Br; L = monobasic bidentate Schiff base ligand; E= P or As) have been synthesized by the reactions of [RuCl_3(PPh_3)_3], [RuCl_3(AsH_3)_3], [RuBr_3(AsH_3)_3] or [RuBr_3(PPh_3)_2(MeOH)] with the appropriate ligands such as anthranilic acid cinnamaldehyde (Hanthcin), anthranilic acid p-tolualdehyde (Hanth-p-tol) and anthranilic cid p-anisaldehyde (Hanth-p-ants). All of these new complexes were characterized using various physics-chemical methods such as elemental analyses, spectral (IR, electronic and EPR), magnetic moment and cyclic voltammetric data. The antibacterical activities of ligands and their complexes have also been determined. An octahedral structure has been hbentatively assigned to all of the new complexes.
