الملخص EN

This project includes Prepration and identification the complexes of amino acid (Serine and Aspartic acid ) with some ions of trace elements which are needed the human body such as (Mo+6 , Se+4 , Vo+2 ) and the prepared complexes which are solid crystals were studies and identification by the following methods .

1- Thermal stability .

2- Solubility (solubility in buffer solution ) .

3- Molar conductivity .

4- Elemental analysis .

5- Determination the percentage rat of the metal in the complexes by spectral of atomic absorption .

6- The spectral studies (Infrared Spectra , UV-Visible ) 7- Determination a quantitative of chloride .

From this identification studies can give the structure formula for the complexes which were prepared with amino acid .

1) Complexes (Vo+2) that is a pyramid have a structure formula as [Vo(AA)2] , when AA= Amino acid (Ser ,Asp ) .

2) Hexa coordination has octahedral which given the structure formula [M(AA)2Cl2 ] when M= (Se+4 ) .

3) Hexa coordination complexes have octahedral which given the structure [M(AA)3 ]Cl3 when M= Mo+6 .

The complex which prepare are soluble crystal solid material in buffer solution (pH= 6-8 ) , that have a good thermal stability ,and Non-Electrolyte except the complexes of Molybdenum (VI) with amino acid (Ser , Asp ) are electrolyte as a ratio (1:3 ) ( Ligand : Ion ) .

The amino acid are behavior bidentate ligands connected with central ion by the oxygen atom in carboxyl group and the nitrogen atom in amino group (-NH2 ).
