  • Abstract

    Coordination compound formed by the interaction of Dihydrothieno[3,4-d]pyridazine with La(III), Ce(III), Sm(III), Th(IV) and UO2(II) are prepared and characterized by elemental analysis, IR, 1H NMR Mass spectra and thermal analysis. The analysis data indicate that the ligand acts as bidentate on chelation, thermogravimetric analysis confirm the presence of coordinates water. The IR spectra indicate that coordination takes place through the nitrogen of amino group and C=O group of pyridazine ring. Antimicrobial activity of selected compounds against some bacterial strains was tested and confirm the antimicrobial activities of the ligand increase on coordination with the metal ion.
