Conducting polymers of a Schiff-base ligand and the corresponding oxo-vanadium(IV) complex have been synthesized, characterized, and studied. The metal-free ligand polymer allows for direct comparison between the properties of the ligand polymer and corresponding conducting metallopolymer. The role of the metal centers in the conducting metallopolymer is elucidated unambiguously.

New series of Schiff base ligand H(2)L and their Cu(II) and Mn(II) complexes derived from azosulfapyrimidine were synthesized and characterized by elemental and thermal studies conductance measurements IR, electronic and EPR spectra. 3D modeling of the ligand indicate that azo group does not participate in complex formation and surface potential on one of the ligand under study indicate that el...

In the title complex, [Cu(C(9)H(9)N(2)O(2))Cl]·2H(2)O, prepared from the Schiff base ligand N'-(2-hydroxy-benzil-idene)aceto-hydrazide and copper(II) chloride, the Cu(II) atom is coord-inated by two O atoms and one N atom from the ligand and by a Cl atom in a distorted square-planar geometry. The two donor O atoms of the tridentate Schiff base ligand are in a trans arrangement. In the crystal s...

one of the best and the most active ways for surveying thermal behaviour of materials is using differential scanning calorimetry. in this paper, the authors have studied thermal behaviour for schiff base ligand and their synthesized cobalt, nickel complexes. in this method, the sample is opposed to a controlled temperature change and its physical properties. here we studied melting point and tg...

In the title complex, [Cu(C13H11N2O)Cl(C6H8N2)], the Cu(II) atom adopts a distorted tetra-hedral geometry being coordinated by the phenolic O atom and the azomethine N atom of the Schiff base ligand N-salicyl-idene 2-amino-pyridine, and by the 2-amino-pyridine N atom and a Cl atom. The pyridyl N atom of the Schiff base and the imino N atom of the 4-methyl-pyridine-2-yl-imino ligand are not invo...

Copper (II), cobalt (II), nickel (II) and zinc (II) complexes of 5-chloroisatin Schiff base (L) (L= Schiff base derived from 5-chloroisatin and 2-methyl-4nitro aniline) were synthesized and characterized. The authenticity of the ligand and its metal complexes had been established by micro analysis, IR, NMR, LC/MS, UV-Vis and electrical conductance measurements. The ligand acts as a bidentate in...

Metal-containing Schiff base/sulfoxides were developed as chiral ligands for Pd(II)-catalyzed asymmetric intramolecular allylic C–H amination reactions. The use of metal-containing base allows tuning the selectivity and reactivity Pd(II)-catalyst, whereby a base-Cu(II)/sulfoxide ligand in combination with Pd(OAc)2 showed best performance. Both internal terminal alkenes applicable, products obta...

abstractinteraction of ni complex(salen= n, n´-ethylene bis(salicylideneimine)) with hen egg-white lysozyme (hewl) was studied by absorption spectroscopy, competitive binding study and thermal denaturation study. the protein binding affinity of ni complex was found to be (3.0×103m−1). the binding plot obtained from the absorption titration data gives a binding constant of 2.4 (± 0.3)×103 m-1. i...

For the spin crossover coordination polymer [Fe(L1)(bipy)]n (where L1 is a N2O22− coordinating Schiff base-like ligand bearing phenazine fluorophore and bipy = 4,4′-bipyridine), there compelling additional evidence of state transition.
