  • Ruthenium(ii) complexes containing RuN4O2 spheres assembled via pyridine-imine-amide coordination. Syntheses, structures, properties and protonation behaviour of coordinated amide
    作者:Satyanarayan Pal、Samudranil Pal

    日期:2002.4.26
    A series of ruthenium(II) complexes of general formula [RuL2] with the pyridine-N, the imine-N and the amide-O donor N-(aroyl)-N′-(picolinylidene)hydrazines (HL) has been synthesized. The ligands differ on the substituent at the para position of the aroyl fragment. The complexes have been characterized by analytical, 1H NMR, electronic absorption spectroscopy and cyclic voltammetry. X-Ray structures of representative complexes have been determined. The lowest energy MLCT (Ru(dπ) → L(π*)) transitions for these complexes are observed at essentially identical wavelength (544 ± 1 nm). The complexes display a metal centred oxidation and a ligand centred reduction in the potential ranges 0.44 to 0.59 V and −1.49 to −1.35 V (vs. Ag/AgCl), respectively. The differences in the metal and ligand redox potentials (ΔE1/2) are practically same (1.94 ± 0.01 V) for all the complexes. The identical MLCT band positions and the same ΔE1/2 values suggest that in this series of complexes, the energy gap between the metal-dπ and the ligand-π* levels is constant. The effective pKa values of the species obtained by protonation of the coordinated amide functionalities in one of the complexes have been evaluated by spectrophotometric titration. The corresponding diprotonated species has been characterized by X-ray crystallography.

  • Some trans-chlorobis(triphenylphosphine)ruthenium(II) complexes with N,N,O-donor N-(aroyl)-N′-(picolinylidene)hydrazines

    DOI:10.1016/j.poly.2004.09.027
    日期:2005.1
    The reactions of [Ru(PPh3)(3)Cl-2] and N-(aroyl)-N'-(picolinylidene)hydrazines (HL): derived from 2-pyridinecarbaldehyde and 4-substituted aroylhydrazines in boiling methanol provide mixed-ligand complexes having the general formula trans-[RuL(PPh3)(2)Cl]. The complexes were characterized by analytical, spectroscopic and electrochemical measurements. The +2 oxidation state of the metal ions in these complexes is confirmed by their diamagnetic nature in the solid state and electrically non-conducting behavior in solution. The X-ray structure of a representative complex has been determined. The metal ion is in a distorted octahedral N2OP2Cl coordination sphere. The monoanionic pyridine-N. imine-N and deprotonated amide-O donor ligand and the chlorine atom form an N2OCl square-plane around the metal centre and the P-atoms of the PPh3 Molecules OCCUPY the remaining two axial sites. The P-31 NMR spectra of all the complexes in CDCl3 solutions are consistent with the irons orientation of the PPh3 molecules. Electronic spectra of the complexes in dichloromethane solution display several bands in the range 590-261 nm due to metal-to-ligand charge transfer and intraligand transitions. Cyclic voltammograms of the complexes in dimethylformamide solution display the reversible Ru(III)/Ru(II) couple in the potential range 0.40-0.52 V (versus saturated calomel electrode). The trend in these potential values reflects the polar effect of the substituents on the aroyl moiety of the ligand (L-). (C) 2004 Elsevier Ltd. All rights reserved.
