Popis: The work described in this paper involves the synthesis and structural characterization of Ni(II) complexes derived from dihydroxybenzaldehyde thiosemicarbazones (H3L1, H3L2, H3L3, H3L4) and 1,2-bis(diphenylphosphino)ethane (dppe). Ligands and their Ni(II) complexes were characterized by elemental analysis, IR, UV–Vis, (1H, 13C, 31P) NMR, as well as magnetic moment and X-ray structure analysis. The results so obtained suggest that the thiosemicarbazone ligands behave as a tridentate ligand which were coordinated with Ni(II) ion through O, N and S atoms. Furthermore, the dppe ligand was coordinated with Ni(II) ion through the P atom. It is concluded that all Ni(II) complexes have a Square-planar geometry.
