تحضير و تشخيص بعض معقدات العناصر النزرة (Mo, Se, V)‎ مع الحامضين الأمينين الألانين و الفنيل الأنين

Abstract EN

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).
