SYNTHESIS & CHARACTERIZATION OF SERIES LIGANDS AND THEIR COMPLEXES WITH (NI2+)
This paper involved ,synthesized of five ligandsfrom coupling reaction of azo compounds with diketone compound or with imine compounds to produce .(azo â€“imine ) compounds or (azo â€“azo ) compounds and (imine â€“imine) compounds which named [( MPA), (HPA) ,(BHI) ,(MHI) ,(TIB) ] . these compounds are used as ligands with (Ni2+) to formation of complexes and study of optimal conditions of complexes such as (stoichiometric study ,mole ratio ,Jop method , PH , concentration of metal ,and ligands ,molar conductance ) . All ligands with complexes were characterized by (UV-VisÂ spectra ,FT.IR â€“spectra ,(C.H.N) â€“analysis , melting points ).
