New Complexes of Zn(II), Cd(II) and Hg(II) with Ligand Derived from 1-(3,5-diiodo, 2-hydroxy, 4-methyl phenyl), 2-phenyl sulfanyl ethanone

In this paper are presented the conditions to obtain several new complexes through the interaction of Zn(II), Cd(II) and Hg(II) with 1-(3,5-diiodo, 2-hydroxy, 4-methyl phenyl), 2-phenyl sulfanyl ethanone in the molar ratio of 1:2. Also, their characterization was performed by chemical analysis, thermogravimetry, X-ray diffraction and IR absorption spectroscopy. The new complexes crystallize in the monoclinic system with Zn(II), Cd(II) or Hg(II) tetracoordinated as central atoms in tetrahedral structures. The obtaining reactions of these complexes can be used in gravimetric determination of Zn(II), Cd(II) and Hg(II) with an error of 0.25%.
