Several M(iii) Complexes of the type [M(LL’).2H2O]Cl (where LL’=tetradentate Schiff bases & M=Ti(iii), Mn(iii) or Fe(iii) have been synthesised by the reaction of respective Schiff bases having the donor groups (O,N) viz., O-hydroxyacetophenone tetramethylene diamine (OHAOTMDA), O-hydroxyacetophenone O-phenylenediamine (OHAOPDA) and b-hydroxynaphthaldehyde tetramethylene diamine (b-HNATMDA) in 1:1 molar ratio. All the complexes have been characterised on the basis of elemental analyses, spectral (IR, Electronic), electrochemical and magnetic data. The complexes have also been screened for antibacterial properties.
