Preparation and characterization of a number of complexes of Mn (II), Co (II), Ni (II), Cu (II), Hg (II) ions With a mixture of saccharin ligands, barbituric acid and thiobarbituric

Abstract

This thesis includes, preparation and diagnosis of new twenty-one complex Of ions Mn (II) , Co (II) , Ni (II) , Cu (II) , Hg (II)

With a mixture of saccharin legends and Barbituric / Thiobarbituric acid.

The work included  interaction of elements ions above With a mixture of saccharin legends and Barbituric / Thiobarbituric acid with Mole fraction (1: 1: 1) (Metal : saccharin : Barbituric or Thiobarbituric acid )  complexes were  Diagnosed that have been prepared by fusion degrees , the  magnetic  sensitivity , careful analysis of the elements (CHNS)   , molar Electrical conductivity techniques and and infrared spectrum , electronic spectrum and Nuclear Magnetic Resonance spectrum of the proton (H.NMR) techniques .

and Through the results that were obtained chemical formulas were suggested for the first part complexes were as follows: -

]M(BA) (sac)(H₂O) ₄  [ Cl

] M(TBA) (sac)(H₂O)₄ [ Cl

Whereas

Mn (II) , Co (II) , Ni (II) , Cu (II)  M=

BA = Barbituric acid.

TBA = Thiobarbituric acid .

sac= Saccharine .

And it had a octahedral geometric shape Where Saccharine was linked to the central metal by nitrogen atom  And Barbituric acid was linked to the central metal by  oxygen atom.

And Thiobarbituric acid was linked to the central metal by sulfur atom.

And complexes Hg (II) have chemical formulas

Cl[Hg(BA)(sac)]

Cl [Hg(TBA)(sac)]

With linear geometric structure.

Where Saccharine was linked to the central metal by nitrogen atom  And Barbituric acid was linked to the central metal by  oxygen atom.

And Thiobarbituric acid was linked to the central metal by sulfur atom.
