In this work, new complexes of some lanthanide ions metals, such as (La+3, Nd+3, Er+3, Gd+3and Dy+3) with Schiff bases that derived from the antipyrine compound were synthesized. This ligand can be synthesized from condensation dimedone with 4-aminoanitpyrine in microwave irradiation and were identified using (FT-IR spectroscopy, UV-Visible spectroscopy, CHNO analysis, LC-mass, 1H-NMR, 13C-NMR and TGA analysis). The complexes were characterized by FT-IR, UV-Visible, CHNO analysis, conductivity measurement, magnetic susceptibility, and theromgravimatric analysis. From stoichiometry of metal to ligand and all measurements was proposed formula of complexes and a molar ratio (2-2) (metal – ligand) to give the. The bioactivity of the prepared (L) and its complexes were assessed using antibacterial activity, and the results revealed significant activity against some fungi and bacteria.
