Chiral Schiff base ruthenium(III) complexes: Synthesis, characterisation, catalytic and antibacterial studies

Abstract

Chiral Schiff base ruthenium (III) complexes of the type [RuX(LL')(EPh3)] (X = Cl or Br; LL' = chiral Schiff base; E = P or As) have been synthesised by the reactions of [RuX3(EPh3)(3)] or [RuBr3(PPh3)(2) (MeOH)] with appropriate Schiff bases having the donor groups (O,N) viz., bis[3(1'-naphthyl)salicylidenecy clohexanediimine](L1)orbis[3(1'-naphthyl)salicylidenepropylenediimine] (L2) or bis[3(1'-naphthyl)salicyliden ediphenyldiimine] (U) in 1: 1 molar ratio. The characterisation of the complex was done by elemental analyses and spectral (IR, UV-visible and EPR), electrochemical and magnetic moment data. An octahedral structure has been tentatively proposed for all the new complexes. The catalytic and antibacterial activities have also been carried out for these new complexes.
