Abstract:

In this study, Schiff base ligands of (E)-3-(2-aminophenylimino)indolin-2-one, (L1); (E)-3-(2-amino-5-nitrophenylimino)indolin-2-one, (L2); and (E)-3-(2-amino-5-chlorophenylimino) indolin-2-one, (L3) were synthesized via condensation reaction of isatin with o-phenylenediamine, 4-nitro-o-phenylenediamine and 4-chloro-o-phenylenediamine respectively. All the synthesized compounds were characterized by various of physicochemical techniques such as melting point, elemental analysis, infrared spectroscopy, and 1H nuclear magnetic spectroscopy. Conductivity studies of these ligands were investigated by impedance analyzer which the samples were prepared in the form of tablets. The electrical conductivities of the prepared compounds were measured by applying alternating current (ac) voltage. The conductivity values were calculated and result obtained shows that L2 has the highest conductivity value, followed by L3 and L1.
