The reaction of warm EtOH solutions of ninhydrin and
thiosemicarbazide with NiCl2.6H2O (in EtOH) and Zn(AcO)2·2H2O
yielded a tetrahedral and square planar complexes of Zn(II) and Ni(II)
respectively in a 1:1:1 mole ratio using the template method of
The Schiff base, thus formed acted as a monobasic tridentate ligand via
ONS binding sites.
The compounds were characterized by conductometric,
magnetochemical measurements, AAS, IR, NMR, and UV-Vis spectra.
Besides, voltammetric study of Ni (II) complex was carried out in DMSO
solution in the presence of supporting electrolyte to characterize its
redox nature. The biological activities of the complexes were also
