Synthesis and Characterization of 5-Chloro 2-furaldehyde Thiosemicarbazone and Its Nickel, Copper and Zinc Complexes

The aim of the present study was to synthesize and characterize of divalent metal ions of Nickel, Copper and Zinc complexes of 5-chloro 2-furaldehyde thiosemicarbazone. Firstly ligand was prepared from the reaction between 5-Chloro-2-furaldehyde and thiosemicarbazide, the second step involved the synthesis of Ni(II), Cu(II) and Zn(II) complexes of 5-chloro 2-furaldehyde thiosemicarbazone. The prepared compounds (ligand or complex) was characterized using different analytical techniques such as elemental analysis, and IR, UV, Mass and 1H NMR tests, the results obtained showed that the ligand and its Ni(II), Cu(II), Zn(II) and Co(II) complexes of 5-chloro 2-furaldehyde thiosemicarbazone were prepared successfully.
