Synthesis of Two Potentially Heptadentate (N4O3) Schiff-base Ligands Derived from Condensation of Tris(3-aminopropyl)- amine and Salicylaldehyde or 4-Hydroxysalicylaldehyde. Nickel(II) and Copper(II) Complexes of the Former Ligand
Two potentially heptadentate (N4O3) tripodal Schiff-base ligands: tris(3(salicylideneimino)propyl)amine (H3L1) and tris(3-(4'-hydroxysalicylideneimino)propyl)amine (H3L2) have been prepared and characterized by various spectroscopic methods (IR, FAB-MS, NMR). They are derived from the condensation reactions of tris(3-aminopropyl)amine (tpt), with 3 equivalents of either salicylaldehyde or the r...
متن کاملSynthesis, characterization, antioxidant and antimicrobial activities of a heptadentate N4O3-type Schiff base ligand and its metal complexes
Mo(III), Fe(III), Cd(II), Zn(II), Cu(II) complexes based on Tris[2-salicylaldeneimino)ethyl]amine (H3saltren) have been successfully synthesized. Newly prepared compounds have been characterized by 1H-NMR, 13C-NMR, IR and UV–VIS spectroscopy techniques. The spectral studies confirmed the ligand coordinates the metal ion to form complex via the oxygen and nitroge...

A new unsymmetric thioether diamine N - ( 2 - ( 2 - aminophenylthio) ethyl) benzene - 1 , 2 - diamine was prepared through the nucleophilic substitution of cysteaminium chloride with 1 - chloro - 2 - nitrobenzene and then the nitro groups of prepared compuond converted to the amine by zinc powder and ammonium chloride. Then, unsymmetric Schiff bass ligand 2 - ((( 2 - (( 2 - (( 2 - (( 2 - hydrox...
