Synthesis and characterisation of ruthenium(III) complexes containing triphenylphosphine/arsine and Schiff bases

摘要

Several new hexa-coordinated ruthenium(III) complexes of the type [RuX(EPh3)(LL')] (where X = Cl, Br; E = P, As; HLL'H = H(2)Acac-en, H(2)Bzac-en, H(2)Acac-pn and H(2)Bzac-pn) have been synthesised by reacting [RuCl3(PPh3)(3)], [RuCl3(AsPh3)(3)], [RuBr3(AsPh3)(3)] or [RuBr3(PPh3)(2)(MeOH)] with tetradentate Schiff bases. The Schiff bases deprotonate and behave as binegative tetradentate chelating ligands. All complexes have been characterised by elemental analyses, IR, electronic spectra, EPR and cyclic voltammetric data. [References: 35]
