Synthesis, characterization and antibacterial properties of symmetric 1,1?-ferrocene derived Schiff-base ligands and their Co(II), Cu(II), Ni(II) and Zn(II) chelates

Symmetric 1,1′-dimethylferrocene derived Schiff-base ligands have been prepared by the condensation reaction of 1,1′-diacetylferrocene with 2-aminopyrazine, 2-aminopyridine and 2-aminothiazole respectively. Their transition metal chelates, of the type [M(L)]Cl2 [M = Cu(II)] and [M(L)(Cl2)] [M = Co(II), Ni(II) and Zn(II)] have been prepared. The synthesized Schiff-base ligands and their metal(II) chelates have been characterized by their physical, analytical and spectral data.
