Abstract EN

The reaction of LAs-Cl8 : [ (2.2- (l-(3.4-bis(carboxylicdichloromethoxy)-5-oxo-2.5- diliydrofuran-2-yl)ethane - 1.2-diyl)bis(2.2-dichloroacetic acid)]with sodium azide in ethanol with drops of distilled water has been investigated .

The new product L-AZ :(3Z .5Z.8Z)-2- azido-8-[azido(3Z.5Z)-2-azido-2.6-bis(azidocarbonyl)-8.9-dihydro-2H-1.7-dioxa-3.4.5- triazonine-9-yl]methyl]-9-[(l-azido-l-hydroxy)methyl]-2H-l,7-dioxa-3.4,5-triazonine - 2.6 - dicarbonylazide was isolated and characterized by elemental analysis (C.H.N) .

!H-NMR , Mass spectrum and Fourier transform infrared spectrophotometer (FT-IR) .

The reaction of the L-AZ withM+n: [ ( VO(II) .

Cr(III) .Mn(II) .

Co(II) .

Ni(II) .

Cu(II) .

Zn(II) .

Cd(II) and Hg(II)] has been investigated and was isolated and characterized by FT- IR .

UV-Visible .electrical conductivity, magnetic susceptibilities at 22 C° .

Atomic absorption and molar ratio Spectroscopic evidence showed that the binding of metal ions were through the azide(f.i- I.I-N3) Triazonine(3.5 -N3) and carboxyl moieties .

resulting in a six - coordinating metal ions (Cr(ni).Mn(II).Co(II).Ni(II) and Cu(II) ) .The VO(II) , Zn(II) .Cd(II).

andHg(E) were coordinated through azido Q1-I.I-N3) .

triazonine(3.5-N3) only forming square pyramidal for VO(II) and tetrahedral geometry for Zn(II) , Cd(II) .and Hg(II)β,B for Ni(II) , Cr(m) complexes were calculated too .

The molar ratio and metal estimation showed .

the ratio of L- AZ to metal ions was (10:1) ; (M/L)
