摘要:
Several hexa-coordinated ruthenium(II) carbonyl complexes of the type [Ru(CO)(B)(L)] (B = PPh3, pyridine (py), piperidine (pip) or morpholine (morph); H2L = tetradentate Schiff bases) have been prepared by the reactions of [RuHCl(CO)(PPh3)2(B)] (B = PPh3 or py or pip or morph) with appropriate Schiff bases having the donor groups O,N viz., o-hydroxyacetophenoneethylenediimine, H-2(o-hyacen); o-hydroxyacetophenonepropylenediimine, H-2(o-hyacpn); o-hydroxyacetophenonetetramethylenediimine, H-2(o-hyactn), and o-hydroxyacetophenone-ortho-phenylenediimine, H-2(o-hyacopn), in 1:1 molar ratio. The complexes have been characterised on the basis of elemental analyses and spectral (IR, electronic, H-1 and P-31 NMR) data. The antibacterial activities of these new complexes were also tested.
