    Studies on Ni (II) Complex Derived from Ninhydrin Di- Semicarbazone
    (Addis Ababa Universty, 2007-08) G/Selassie Gizaw; Raju V.J.T. (Professor)
    The disemicarbazone derivative of ninhydrin (NDSC) was synthesized by the 1:2 condensations between ninhydrin and semicarbazide hydrochloride in ethanolic medium. It was characterized on the basis of mass spectrum, 1H-NMR, 13C-NMR, IR, UV-vis and analytical data. The Ni (II) complex of NDSC was successfully synthesized in better yield from template procedure. The complex was characterized by analytical, conductance, IR, UV-vis and magnetic susceptibility data. The results suggest that the complex with the molecular formula [Ni-NDSC(H2O)Cl]Cl has octahedral geometry with the ligand behaving as a neutral ONNO donor.
