Synthesis, Characterization and Biological Activity: Co(II), Ni(II), Cu(II) and Zn(II) Complexes of Schiff Bases Derived from 4-Cyanobenzaldehye and 4-Amino-5-Mercapto-3-Methyl/Ethyl-1,2,4-triazolesBy Singh K., Manish Kumar, Garg G.
Abstract: Co(II), Ni(II), Cu(II) and Zn(II) complexes of bidentate Schiff bases derived from the condensation of 4-amino-5-mercapto-3-methyl-1,2,4-triazole and 4-amino-3-ethyl-5-mercapto-1,2,4-triazole with 4-cyanobenzaldehyde have been synthesized. The synthesized Schiff bases and their metal complexes were then characterized by elemental analysis, spectroscopic methods (IR, NMR, electronic spectra), magnetic moment measurement and thermogravimetric techniques. The electronic spectra and magnetic moment studies suggest octahedral geometry for Co(II), Ni(II) and Zn(II) complexes and square planar geometry for …
