M(III) complexes of Ti,Fe and Mn with schiff bases derived from 2-amino-4-ethyl-5-hydroxy benzaldehyde N,N’-dimethyl 4-aminobenzaldehyde and thiocarbohydrazide were synthesised and characterised by elemental analyses, molar conductance measurements,magnetic susceptibility determination, electronic and IR spectral studies. Based on these studies,octahedral geometry has been proposed for all the syntesised complexes. Schiff bases as well as their corresponding M(III) complexes were screened for their antimicrobial activities.
