Here, new N,N′-dipyridoxyl(4,4''-diaminodiphenylether) Schiff-base ligand has been synthesized and characterized by IR, 1H NMR and mass spectrometry. Also, geometry optimization and theoretical assignment of IR spectrum of the ligand have been computed by employing density functional theory (DFT) method. Two pyridine rings and benzene rings in the bridge region are not in the same plane. The ca...

First, Schiff base iminopyridine ligand has been prepared by the condensation between primary amine, dimethylaniline and active carbonyl group of pyridine carboxaldehyde, then related complexes were synthesized in methanol solution. The ligand and metal complexes have been characterized by elemental analysis, UV, IR, 1 H NMR and 13CNMR spectroscopy. The spectroscopic data of metal complexes ind...

The reaction of [Ru(L)2(H2biim)](ClO4)2 [L1 = 2,2¢-bipyridine (bpy) or L2 =  2-(phenylazo)pyridine (pap) and H2biim = 2,2¢-biimidazole] with Au(tht)Cl (tht = tetrahydrothiophene) in presence of base in methanol produced a terametallic cationic complex [{Ru(L)2(biim)}<s...

A new tris-(2-aminoethyl)amine (TREN) capped tripodal Schiff base ligand has been developed by mimicking structural features of a natural siderophore, Bacillibactin, by substituting the catechol units with salicylaldehyde and employing amino acid as spacer. Synthesis of the ligand N-[2-[bis[2-[[2-[(2-hydroxyphenyl)methylamino]acetyl] amino]ethyl]amino]ethyl]-2-[(2-hydroxyphenyl)methylamino]...
