Synthesis, Characterization and Molecular Modeling of Nickel (II) Complexes with Semicarbazones and Thiosemicarbazones
Journal Title: International journal of Emerging Trends in Science and Technology - Year 2014, Vol 1, Issue 9
Abstract
Ni (II) complexes of ligands pyridine-3-formamide thiosemicarbazone (L1), pyridine-3-formamide semicarbazone(L2), pyridine-2-formamide thiosemicarbazone (L3) and pyridine-2 -formamide semicarbazone (L4) have been synthesised. The ligands were characterised on the basis of elemental analyses, IR, 1HNMR studies while that of the complexes were characterised by elemental analyses, molar conductance, magnetic moment, IR, electronic. On the basis of elemental analyses and molar conductance data the complexes were found to have general composition [Ni(L)2X2] (where L=L1, L2, L3 and L4 , X = Cl– ,NO3 – ]. On the basis of IR, electronic spectra of complexes, octahedral geometries were found with planar coordination of the ligand around Ni2+ ion. Molecular modeling confirmed octahedral geometry.
