Synthesis, Characterization, Metal Ion Intake and Antibacterial Activity of Schiff Base Complexes of Zr(IV) and Th(IV) Derived From Di-α-Formyl Methoxybis (3-Pentadecenylphenyl) Methane [DFMPM] and Ethylenediamine

The Zr(IV) and Th(IV)-di-α-formylmethoxy bis(3-pentadecenylphenyl)methane (DFMPM) ethylediamine complex were synthesized and characterized by elemental analysis, conductivity measurements, electronic, infrared, ¹HNMR spectral measurements, metal ion intake and antibacterial studies. The conductance measurements indicate that all the complexes are non-electrolytes. The infrared spectra indicate the coordination of imino nitrogen, M-N and M-O bonds. UV-visible spectra could not provide structural details of these complexes. 1HNMR data are consistent with IR spectral data. The results indicate that both Zr(IV) and Th(IV) ions are octacoordinated and have moderate antibacterial activity. The metal ion intake indicates the ligand can be used for the extraction of these metals from water.
