Synthesis, Spectral and Biochemical Studies of New Complexes of Mixed Ligand Schiff Base and Anthranilic Acid

Abstract

In this research, new mixed ligand Schiff base complexes of Mn(II), Co(II), Ni(II), Cu(II), Cd(II), and Hg(II) are formulated from the Schiff base ( L) resulting from o-phathalaldehyde (o-PA) with p-nitroaniline (p-NA) as a primary ligand and anthranilic acid as a subordinate ligand. Diagnosis of prepared ligand and its complexes is done by spectral methods as mass spectrometer; 1 H -NMR for ligand Schiff base FTIR, UV-Vis, molar conductance, elemental microanalyses, atomic absoption and magnetic susceptibility. The analytical studies for the all new complexes have shown octahedral geometries. The study of organicperformance of ligand Schiff base and its complexes show various activity agansit four type of bactria two gram (+) and two gram (-) .

“…e observed peak at 282.2 nm confirms the π−π * transition for the cyclic (benzene) ring and the peak at 314.5 nm was attributed to n−π * transitions of nonbonding electrons that exist on the nitrogen atom (-HC�N-). e L 2 spectra band shows two peaks: one observed at 309.4 nm for the π-π * transition of an electron in the aromatic ring [19,24] and at 333 nm for the n−π * transition of lone-pair electrons found on the nitrogen atom (Figure S2) [25,26].…”
