This study involves the synthesis and conductivity of phenylthiosemicarbazide
derivative and metal complexes. New copper (II) and nickel (II) complexes were
synthesized with 2-pyridinecarboxyaldehyde N(4)-phenylthiosemicarbazone. The
ligands form a thiol-thione tautomerism presenting several forms of donor atoms and
form four or five-member chelate rings when bind to metal ion. The metal complexes
were dissolved in carboxyl methyl cellulose (CMC) to form a thin film. All the ligand
and complexes were characterized by FT-IR spectroscopy, UV-vis spectroscopy,
thermo gravimetric analyses and elemental analysis. In addition, the conductivity of
copper (II) complexes and nickel (II) complexes were studied by using Cole- Cole Plot
of Electrochemical Impedance Spectroscopy (EIS). The Schiff bases of copper
complexes excellently have a high conductivity.
