Thermal Observation of Zr (IV) and UO2 (VI) Complexes Derived from Thiazole Schiff Base

Bidentate Schiff Base derived from quinolone Ligands Oxovanadium (IV) Complexes

Synthesis and Characterization of Cr(III), Mn(III), Fe(III), VO(IV), Zr(IV) and UO2(VI) Complexes of Schiff Base Derived from Isonicotinoyl Hydrazone

2-hydroxy-5-chloro-3-nitroacetophenone isonicotinoyl hydrazone as a Schiff base ligand and its complexes with Cr(III), Mn(III), Fe(III), VO(IV), Zr(IV) and UO2(VI) metal ions have been synthesized. The ligands as well as their metal complexes were well characterized using various physicochemical techniques such as elemental analyses, molar conductance measurements, magnetic measurements, therma...

Synthesis and characterization of some transition metal complexes of Schiff base derived from 2,4 - dihydroxybenzaldehyde

Abstract New N2O2 type Schiff base has been designed and synthesized by condensing 2,4 dihydroxy benzaldehyde and α-naphthylamine in ethanol. Solid metal complexes of the schiff base with Cu(II), Ni(II) and Zn(II) metal ion were synthesized and characterized by elemental analysis, magnetic susceptibility, molar conductance, IR, UV-Vis and ‘H NMR spectral studies. The data shows that the c...

Synthesis and Characterization of Metal Complexes with New Unsymmetrical Schiff Base Ligand Derived from 2-Aminoethanethiol

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...

Bidentate Isatin Schiff Base Ligands Oxovanadium (IV) Complexes

The aim of the present study is to synthesize the oxovanadium complex of the V3+ ion with isatin sciff bases. Spectroscopic methods have been used to confirm these models of complexation and to understand the structures of the species formed in methanolic solution. We also have isolated a complex of Vanadium (III) with isatin schiff bases in the solid phase.
