Abstract

Formation of lanthanide (La, Ce & Nd) metal ion complexes of o-Vanillinphenylalanine (o-Vanphen) were prepared by the one-pot template, and having the general formula K[Ln(o-Vanphen)2(H2O)2].H2O where Ln stands for La(III), Ce(III) & Nd(III), o-Vanillin=C8H8O3, phenylalanine=C9H11NO2. The complexes were synthesized in the absolute ethanol the coordination of the complexes were determined by elemental analysis, UV-vis. , molar conductance and all the prepared compounds have been characterized by Infrared spectroscopy (FT-IR) and 1H-NMR. The results suggest that the metal ions bonded to the ligand through the phenolic oxygen, carboxylic oxygen groups and the imino nitrogen, spectra of their complexes shows that the ligand acts as a tridentate manner through (ONO) donor atoms. Ln(III) metal ions are eight coordinate C.N=8 in those complexes. The analytical data of the complexes show the formation of 1:2 (M:L) metal to ligand ratio. The synthesized products were examined for antimicrobial activity against a variety of test organisms.
