Compounds of Mn(II), Co(II) and Ni(II) with Ligand Derived from Morfolin-4 Carboditioic Acid-2(3,5 Diiod, 4 Methyl 2 Hydroxiphenyl) 2-Oxoethylesther

In order to obtain new compounds of transitional metals having applications in analytical chemistry, we synthesized and studied compounds of Mn(II), Co(II) and Ni(II) with ligand derived from morfolin-4 carboditioic acid-2(3,5-diiod, 4 methyle 2-hydroxiphenyl) 2-oxoethylesther in the molar ratio of 2:1 (ligand to central atom). The characterization of new compounds was performed by means of chemical analysis, derivatographic thermogravimetry, IR absorption spectroscopy, ESR spectroscopy and X-ray diffraction. The investigated compounds are paramagnetic and crystallize in monoclinic system with central atoms Mn(II) , Co(II) or Ni(II) hexacoordinated in octahedral structures. The study of the obtaining reactions of these new compounds supports their use in gravimetric determination of Mn(II), Co(II) and Ni(II).
