Abstract
Several new hexa-coordinated ruthenium(III) complexes of the type [RuX(EPh3)(LL′)] (X=Cl, Br; E=P, As; LL′ = anthacac, anthdibm, 2-amtpacac or 2-amtpdibm) have been synthesised by reacting [RuCl3(PPh3)3], [RuCl3(AsPh3)3], [RuBr3(AsPh3)3] or [RuBr3(PPh3)2(MeOH)] with tetradentate Schiff bases such as bis(anthranilic acid)acetylacetimine (H2-anthacac), bis(anthranilic acid)dibenzoylmethimine (H2-anthdibm), bis(2-aminothiophenol)acetylacetimine (H2-2-amptacac) or bis(2-aminothiophenol)dibenzoylmethimine (H2-2-amtpdibm). All of the complexes have been characterised by elemental analyses, IR, electronic spectra, EPR, magnetic moment and cyclic voltammetric data. An octahedral structure has been tentatively proposed for the complexes. These complexes were also tested for their antibacterial properties.
