A new heterocyclic Schiff base ligands and their complexes have been synthesized from 4-aminoantipyrine, thiophene-2-Carboxaldehyde and 2-amino benzoic acid. The ligands and its transition metal complexes of Cu (II), Co (II), Ni (II) and Zn (II) are characterized by UV, FTIR NMR and Mass studies. The antibacterial and antifungal activity of the ligands and the metal complexes were tested.

Three new hydroxyl-substituted Schiff-bases containing ferrocenyl moieties were synthesized, and their antioxidant and anticancer activities were evaluated. Among the synthesized hydroxyl-substituted Schiff-bases, compound 1 containing both ferrocenyl and o-dihydroxyl groups exhibits the highest antioxidant and anticancer activities. Flow cytometric analysis showed that compound 1 is capable of...

A series of mononuclear lanthanide complexes with chiral Schiff base ligands [Ln(FTA)(3)L] [Ln = Dy(1), Sm(2), Eu(3), Gd(4), and Tb(5), L = (S,S)-2,2'-Bis(4-benzyl-2-oxazoline)] were synthesized and characterized. Among these complexes, complex 1 represents the first example of mononuclear lanthanide complexes displaying single-ion magnet behavior and ferroelectricity.
