Abstract: | New ruthenium(III) complexes of the [RuY(LL)(E)2] type (Y = Cl or Br; LL = tridentate Schiff bases; E = PPh3 or AsPh3) have been synthesised by reacting [RuX3(EPh3)3] (X = Cl, E = P; X = Cl or Br, E = As) or [RuBr3(EPh3)2(MeOH)] with Schiff bases having the donor groups (O, N, X) viz., salicylaldehydethiosemicarbazone (X = S), salicylaldehydesemicarbazone (X = O), o-hydroxyacetophenonethiosemicarbazone (X = S) and o-hydroxyacetophenonesemicarbazone (X = O). The new complexes were characterised by elemental analysis, spectral (i.r., electronic spectra, e.p.r.), magnetic moment and cyclic voltammetry data. Biocidal activity studies were also carried out for the new complexes. |
