Preparation and characterization of some trace element complexes (Mo, Se, with the following two amino acids: alanine and phenyl

الملخص

This project includes Preparation and identification the complexes of amino acid
(Phenylalanine and Alanine ) with some ions of trace elements which are needed the
human body such as (Mo+6,Se+4,V+2) and the prepared complexes which are solid
crystals were studies and identified by many ways like Elemental analysis (C.H.N) ,
spectral studied (Infrared Spectra , UV-Visible ) . Spectral of atomic absorption
From this identification studies can give the structure formula for the complexes
which were prepared with amino acids .
1 – Complexes (VO+2) that is a pyramid have a structural formula as [VO(AA)2] , when
AA= Amino acid (Phe ,Ala) .
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 at (pH
= 6-8 ), that have a good thermal stability , and Non – Electrolyte except the
complexes of Molybdenum(VI) with amino acid (Phe,Ala) are electrolyte as a ratio
(1:3) (Ligand : Ion ) .
The amino acids are behavior bidentate Ligands connected with central ion by the atom
in carboxyl group and the nitrogen atom in amino group (-NH2)
