Ahmed, Riyadh; I.Yousif, Enaam	Synthesis and Characterization of Some Mixed-Ligand Complexes Containing Azo Dye and 1,10-phenanthroline with CoII, ZnII, CdII and HgII Ions	2017	17	.pdf	application/pdf	4998	366	75	(H2O) Cl] A similar produce described to that mentioned in preparation of CoII complex was used to prepare the complexes of [HL] with [ZnII ,CdII and HgII],ions . The bands arising due to vibrational v(C=N)phen. mode at (1645.28)cm-1 frequency in the free 1,10-phenanthroline were observed to be shifted to lower frequencies , and appears at (1620.21)cm-1,(1624.06)cm-1, (1618)cm-1 and (1614.42)cm-1 for complexes of CoII, ZnII, CdII and HgII respectively .The movement of v(N=N) stretch of the complexes to relatively lower frequencies ,at ( 1425.04), (1423.47), (1421) and (1450.47)cm-1 for complexes CoII, ZnII, CdII and HgII respectively , compared to that of free dyes or ligand indicates coordination via the N=N group	cache/iajs-152.pdf	txt/iajs-152.txt
