Synthesis, characterization, theoretical study and biological evaluation of Schiff base and their La(III), Ce(IV) and UO2(II) complexes

ABSTRACT. A new three metal complexes of La(III), Ce(IV) and UO2(II) ions have been synthesized based on a Schiff base derived from the condensation L-histidine anisaldehyde. All prepared compounds were characterized by different spectroscopic techniques Density-functional theory (DFT) calculations. The proposed to an octahedral structure investigated results. optimized shape, numbering system, dipole moment vector Ligand La, Ce, UO2 (1:1) chelates investigated. ligand exhibit moderate action against all bacteria tested, with P. aeruginosa, Klebsiella sp., E. faecalis respectively being order inhibition.
