摘要: In this study, we synthesized the amine compounds (1-p-diphenylmethane-2-hydroxyimino-2-(1-arylamino)-1-ethanones) [HL1 (2) and HL2 (9)] as starting material, then prepared quadridentate tetraaza Schiff base ligands [H2L3 (3) H2L4 (10)] from reactions of with 1,2-phenylenediamine. A new series mononuclear Ru(III) (4), (11), heterodinuclear Ru(III)–Mn(II) (8), (15), Ru(III)–Ni(II) (7), (14), Ru(III)–Cu(II) (5), (12) heterotrinuclear Ru(III)–Cu(II)–Ru(III) (6), (13) complexes have been using oxime-imine ligands, 1,10-phenanthroline monohydrate, ruthenium(III) a second metal salts. The were characterized by elemental analysis, molar conductivity, IR, ESR, ICP-OES, magnetic moment measurements thermal analyses studies. free also 1H-NMR spectra. coordinates through its nitrogen donors in equatorial position loss one oxime protons concomitant formation an intra-molecular hydrogen bond. Stoichiometric spectral results indicated that metal: ligand ratios found to be 1:1 while 2:1 dinuclear 3:2 trinuclear complexes.
