New azo - schiff base ligand (NASAR) was synthesized , via the coupling of the
diazonium salt of the schiff base (NAS) with Resorcinol in a basic media .
The two organic compounds were identified with many techniques such (CHN,FTIR
and H
1
NMR for SACAN ), to ensure the ligand preparation , then a UV-Visible study
was prefomed for the ligand and their aqueous mixtures for three of divalent transition
metal ions ( Co, Ni and Cu) to determine the optimal concentration and ?
for mole
ratio solid complex preparation .
Solid complexes were prepared and diagnosed with the previous techniques and other
complenetry techniques as ( electrical coundictivity, magnatic suseptibility ) were
done to determine the complexes formula and suggestion the geometrical of the
complexes.
From whole resulats , they can conculde that the ionic complexes
( cobalt , nickel and copper ) have the geometries ( tetrahedral , square planer and
octaheral ) respectively
