The exceptionally rich coordination chemistry generated by Schiff-base ligands derived from o-vanillin.

Synthesis, Spectral Characterization and Biological Studies of Coordination Compounds of Ruthenium(iii) with Schiff Bases Derived from Sulpha Drugs

The reactions of ruthenium trichloride with Schiff bases derived from sulpha drugs in 1:2 molar ratio leads to the formation of a new series of coordination compounds of type [Ru(L) 2 (H 2 O)Cl]. The Schiff bases used here are o-Vanillin sulphanilamide (oVSaH), o-Vanillin sulphamerazine (oVSmrzH), salicylaldehyde sulphanilamide (SdSaH), salicylaldehyde sulphamerazine (SdSmrzH), 2-hydroxy-1-naph...

Electrochemistry, Thermalanalysis, and Theoretical Study of Vanadyl Schiff Base Complexes

The VO(IV) complexes of tridentate ONO Schiff base ligands derived from 2- aminobenzoicacid and salicylaldehyde derivatives were synthesized and characterized by IR, UV–Vis and elemental analysis. Electrochemical properties of the vanadyl complexes were investigated by cyclic voltammetry. A good linear correlation was observed between the oxidation potentials and the electron-withdrawing charac...

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

Preparation of CuO nanoparticles by thermal decomposition of double-helical dinuclear copper(II) Schiff-base complexes

In this paper, two double helical dinuclear copper(II) complexes of bis-N,O-bidentate Schiff base ligands bis(3-methoxy-N-salicylidene-4,4'-diaminodiphenyl)sulfone (L1) and bis(5-bromo-N-salicylidene-4,4'-diaminodiphenyl)sulfone (L2) were prepared and characterized by elemental analyses (CHN), as well as thermal analysis. Elemental analyses (CHN) suggested that the reaction between ligands and ...

New Tetraaza Schiff Base Ligands and Their Complexes: Synthesis, Characterization and Thermodynamic Studies

Some new symmetrical tetraaza Schiff base ligands containing 2-quinolinecarboxaldehyde moiety formed from condensation reaction of 2-quinolinecarboxaldehyde and o-phenylenediamine derivatives, such as N, Nˊ-bis(2-quinolylmethylidene)-4-methoxy-1, 2-phenylenediimine (L1), N, Nˊ-bis(2-quinolylmethylidene)-4-methy-1, 2-phenylenediimine (L2), N, Nˊ-bis(2-quinolylmethylidene)-4-chloro-1, 2-phenylene...
