Chiral schiff base ruthenium(II) carbonyl complexes: Synthesis, characterization, catalytic and antibacterial studies

Abstract

Chiral Schiff base ruthenium(II) carbonyl complexes of the type [Ru(CO)(L')(B)] (L'= tetradentate Schiff bases; B=PPh3 , pyridine (py), piperidine (pip) or morpholine (morph)) has been synthesised 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., bis[3(1'-naphthyl)salicylidenecyclohexanediimine] (L1) or bis[3(1'-naphthyl)salicylidenepropylenediimine] (L2) or bis[3(1'-naphthyl)salicylidenediphenyldiimine] (L3) in 11 molar ratio. Complexes have been characterized by elemental analyses and spectral (IR, electronic, H-1- and P-31-NMR) 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.
