Preparation of a novel Schiff base ligand namely (N2Z)- N1,N2-bis(furan-2-ylmethylene)oxalamide (L1) and its mixed ligand complexes of some transition metal ions such as (Cr(III), Mn(II), Fe(III), Co(II), Ni(II), Cu(II), Zn(II) and Cd(II), with the synthesized Schiff base ligand (1ry ligand) in the presence of nitrogen containing ligands such as 1,10-phenanthroline and 2,2'-bipyridine (2ry ligand). The Schiff base ligand and its mixed ligand metal complexes were characterized based on many analytical techniques such as elemental analysis, molar conductance, magnetic moment, IR, 1H NMR, UV- Vis...
Preparation of a novel Schiff base ligand namely (N2Z)- N1,N2-bis(furan-2-ylmethylene)oxalamide (L1) and its mixed ligand complexes of some transition metal ions such as (Cr(III), Mn(II), Fe(III), Co(II), Ni(II), Cu(II), Zn(II) and Cd(II), with the synthesized Schiff base ligand (1ry ligand) in the presence of nitrogen containing ligands such as 1,10-phenanthroline and 2,2'-bipyridine (2ry ligand). The Schiff base ligand and its mixed ligand metal complexes were characterized based on many analytical techniques such as elemental analysis, molar conductance, magnetic moment, IR, 1H NMR, UV- Visible, solid reflectance, mass, X-ray diffraction, ESR, thermal analyses techniques (TG and DTG) and different activation thermodynamic parameters, namely E , DeltaH , DeltaS and DeltaG were calculated from their DTG curves to throw more light on the nature of changes accompanying the thermal decomposition process of these complexes. The resultant data revealed that mixed ligand complexes have octahedral structure. The antimicrobial and anticancer (breast and colon cancer) activities of the Schiff base ligand and its mixed ligand complexes were also investigated.
