Synthesis, Characterization, and Biological Study of New Schiff Base and their Complexes for Ni (II), Cu (II) Metal Ions

Abstract

This research describes the synthesis of new ligands Schiff base and their complexes (L), (N2) derived from 5, 5-Dimethyl-cyclohexane-1, 3-dione with 2-Aminopyridine. The ligands were characterized by the elemental microanalysis, melting point, spectroscopic method (FT. IR, 1H-NMR, UV-Vis spectrometer. Reaction of these ligands with some metal salts Ni (II) Cu (II), form a variety of complexes of the general formula: [(M) (L) Cl2], with : M (II) = Ni, and Cu. They were characterized by FT. IR, 1HNMR, UV/Visbil spectroscopy, elemental micro analysis (C.H.N.), magnetic susceptibility, molar conductivity, melting point. The above measurements suggested the following geometry for the prepared complexes demonstrated that the ligand L complexes are non-electrolyte. A study of the biological effectiveness of ligands and complexes was conducted with two types of bacteria and one type: A-An Tetrahedral geometry around metal ion for the Cu, Ni complexes with the ligand [L]. Molar conductivity measurements also of bacteria, and they had an effect on the species studied.
