Synthesis And Characterization Of Nickel (ii) Complexes Derived From 4(5)-imidazolecarboxaldehyde And 24-dihydroxybenzophenone Based Thiosemicarbazones

In this work, two new Ni(II) complexes of 4(5)-imidazolecarboxaldehydeand 2, 4-dihydroxybenzophenone based thiosemicarbazones were synthesized and characterized using different techniques such as elemental analysis, atomic absorption spectroscopy, IRandNMR spectra and other physio-chemical methods. The first ligand (L1): (E)-1-((1H-imidazol-1-yl)methylene)thiosemicarbazide was synthesized by condensing 4(5)-imidazolecarboxaldehyde and thiosemicarbazide together, while the second ligand (L2): (E)-1-((2,4-dihydroxybenzophenyl)(phenyl)methylene)thiosemicarbazide was prepared by the condensation of 2, 4-dihidroxybenzophenone with thiosemicarbazide both in equimolar ratios. Finally, based ontheanalyzedand interpreted data, a square planargeometry was proposed for both Ni[L1] and Ni[L2]complexes.
