Abstract
The synthesis and characterization of several hexa‐coordinated ruthenium(III) Schiff base complexes of the type [RuX(EPh3)2(L)] (E=P or As; X=Cl or Br; L = anion of the Schiff bases derived by the condensation of salicylaldehyde or o‐hydroxyacetophenone with benzoylhydrazine or p‐chlorobenzoylhydrazine) are reported. IR, EPR, electronic spectra and cyclic voltammetric data of the complexes are discussed. An octahedral geometry has been tentatively proposed for all of these complexes. The new complexes have been subjected to a catalytic activity study in the aryl–aryl coupling reaction and also to an antibacterial study.
