The Carboxymethyl chitosan Schiff base (CSB) derivative and its cobalt and nickel complexes (CSB-Co & CSB-Ni) have synthesized. The FTIR results showed the interaction with the amine of Carboxymethyl chitosan and aldehyde confirming the Schiff base formation. The XRD results, in comparison to CMC, displayed weaker peaks, which shows a decrease in crystalline properties and also exhibits the amo...

A new Schiff base and a new series of Co(II), Ni(II), Cu(II), Cd(II), and Hg(II) complexes were synthesized by the condensation of naphthofuran-2-carbohydrazide and diacetylmonoxime. Metal complexes of the Schiff base were prepared from their chloride salts of Co(II), Ni(II), Cu(II), Cd(II), and Hg(II) in ethanol. The ligand along with its metal complexes have been characterized on the basis of...

— Salen type chromium Schiff base complex was synthesized by microwave irradiation. The complex was characterized by UV-visible, FT-IR spectroscopy and EPR spectroscopy. Electrochemical property of chromium complex was tested with the aid of cyclic voltammetry (CV). The synthesized chromium Schiff base complex was electrochemically polymerized and used for the detection of hydroquinone. Chromiu...

Oxovanadium(IV), manganese(II) and copper(II) complexes of a Schiff base ligand derived from 2,4-dihydroxyacetophenone and 1,2-diaminocyclohexane have been encapsulated in the nanocavity of zeolite-Y by flexible ligand method and characterized by metal analysis, IR spectroscopic studies and X-ray diffraction patterns. The encapsulated complexes abbreviated here as CuL-Y, MnL-Y and VOL-Y catalyz...

Transition metal complexes containing Schiff base ligands are of interest to model the active sites of biologically important molecules. In particular, Schiff base derivatives of hydrazones exhibit various bioactivities and play vital role in certain physiological functions as well. Hydrazones and their metal complexes exhibit wide range of biological and pharmaceutical activities that includes...

A new Schiff base ligand (L) obtained by the condensation reaction of N-acetylaceto-otoluidineand 2-aminopropanoic acid (an amino acid), is used to synthesize four mononuclearcomplexes of [MLCl] and [ML2] types (where M = Cu(II) and Zn(II); L = Schiff base) bykeeping the metal and ligand ratio as 1:1 and 1:2 respectively. This ligand and its complexeshave been characterized on the basis of diff...

Schiff base (E)-2-methyl-N-(tetrazolo[1,5-a]quinolin4-ylmethylene)aniline (QMA) was synthesized, and its inhibitive effect for mild steel in 1N HCl solution was investigated by weight loss measurement and electrochemical tests. From the weight loss measurements and electrochemical tests, it was observed that the inhibition efficiency increases with the increase in the Schiff base concentration ...

the corrosion inhibition characteristics of two synthesized schiff bases, namely n, n´-bis(2-hydroxy-6-nitrobenzaldehyde) benzidine  and n, n´-bis(salysylaldehyde) benzidine, on the mild steel corrosion in 2.0 m hydrochloric acid have been investigated by weight loss, potentiodynamic polarization and electrochemical impedance spectroscopy techniques. these studies were carried out at different ...

A Schiff base was prepared from the interaction of ethanolic solutions of 2-hydroxy-1– naphthaldehyde and butylenediamine. The complexes were synthesized by refluxing the mixture of ethanolic solutions of the Schiff base and respective metal (II) chloride. Their solubility, melting point/decomposition temperature, molar conductance, elemental analysis and IR were carried out. The melting point ...
