The present research paper is concerned with synthesis and anti microbial studies of some mixed ligand complexes of certain lanthanide ions with a schiff’s base and diphenyl sulphoxide. They are characterised on the basis of elemental analysis, molecular conductances, molecular mass and metal percentage, magnetic moments and special investigations which include electronic and IR spectra. Antimicrobial activity of the complexes was studied. The complexes confirm to the composition [Ln (MDDA)3 (DPSO)X3] where X=NO3-. The schiff’s base is derived by the condensation of P-anisidane and P-dimethyl amino benzaldehyde. Both the Schiff’s base and DPSO act as neutral monodentate ligands and the complexes appear to be seven-coordinated. The IR data suggests coordination of the ligand to the metal ions in a unidentate fashion through the nitrogen atom of the azomethine group and oxygen atom of the diphenyl sulphoxide molecule. The antimicrobial screening of the ligands and their complexes has been carried out. Thermal decompositions were studied by TG & DTG techniques.
