Abstract: The multidentate ligand, BDTSTHEBD, was synthesized using precursors such as DAAP, DAAD, BDTHEBD and thiosemicarbazide and was characterized by FTIR, NMR and electronic spectroscopy. Co (II) and Ni (II)-complexes were synthesized using the ligand, BDTSTHEBD, and respective metal chloride in a mole ratio of 1:3 and characterized by analytical studies, FTIR and electronic spectroscopy, conductance, magnetic susceptibility measurement and thermal analysis. The non-electrolyte natures of the complexes were ascertained from conductivity measurements. Atomic absorption spectroscopy (AAS) and thermal analysis (TA) techniques were also used to characterize the metal complexes. UV-VIS and magnetic susceptibility measurements indicate octahedral geometry for Co(II)-complex and tetrahedral geometry for Ni(II)-complex.
