Synthesis and Characterization of Some mixed-Ligand Complexes Containing N-acetyl Tryptophan and (2, 2′-bipyridine) with Some Metal Salts	2017	10	.pdf	application/pdf	2653	173	67	General method for the synthesis a) N-acetyl Tryptophan( AcetrpH) was derprotenated according to following reaction: N C H C H C O O H NH C O CH3 H + KOH N C H2C H C O O K NH C O CH3 + H2OEthanol 1 Syn thesis of complexes : An aqueous solution of metal salt (0.5g)(2mmole)of the ligand(Actrp- )dissolved in (20 ml) of ethanol containing(0.12g)(2mmole) of KOH,solution of (1mmole) metal salt contains(0.198g, 0.28g, 0.24g, 0.24g, 0.17g, 0.14g, 0.20g and 0.27g) of MnCl2 .4H2O, FeSO4.7H2O, CoCl2.6H2O, NiCl2.6H2O, CuCl22H2O, ZnCl2, CdCl2.H2O and HgCl2)respectivel in ethanol was added drop wise to mixture. The mixture was stirred for an hour at room temperature,complexes were separated by adding solution of the (2,2′-Bipy) (0.16g,1mmole) in ethanol and by treating the solution with diethylether until complete precipitation.	cache/iajs-596.pdf	txt/iajs-596.txt
