in this paper, cubic nickel oxide nanoparticles were successfully prepared by solid-state thermal decomposition of nickel(ii) macrocyclic schiff-base complex at 450°c for 3 h without employing toxic solvent or surfactant and complicated equipment. nickel(ii) macrocyclic schiff-base complex was synthesized by the reaction of 1,2-bis(2-formyl-3-methoxyphenyl)propane, nicl2•6h2o and 1,3-phenylened...

A novel and simple approach to the synthesis of macrocyclic Schiff base ligand resulted from the condensation of bisaldehyde and ethylenediamine was prepared (7, 8, 15, 16, 17, 18-hexahydrodibenzo (a, g) (14) annulene) (L) and its complexes were synthesized and characterized using different physicochemical studies as elemental analysis, FT-IR, H NMR, conductivity, magnetic properties, thermal a...

The novel titanium(IV) complexes of composition [TiCl2(SB)2] have been synthesized by reacting TiCl4 and Schiff bases (SBs) where (SBs = A1( tetracycline hydrochloride schiffs base) ;B1(Streptomycin schiffs base ) ;C1( Ceffixime schiffs base) ;D1( ampicillin schiffs base) in fixed molar ratio 1:2. Titanium and chlorine estimation were estimated by gravimetrical and Volhard method respectively. ...

Schiff bases and their metal-complexes are versatile compounds exhibiting a broad range of biological activities and thus actively used in the drug development process. The aim of the present study was the synthesis and characterization of new Schiff bases and their copper (II) complexes, derived from L-tryptophan and isomeric (2-; 3-; 4-) pyridinecarboxaldehydes, as well as the assessment of t...

Two Schiff base ligands Ampp-Sn 1 and Bmpp-Sn 2, afforded by a condensation reaction between sulfanilamide and the respective acylpyrazolone carbonyl precursors, their Mn(II), Co(II), Ni(II), and Cu(II) complexes prepared by the reaction of ligands and corresponding metal salts in aqueous solutions, were synthesized and then characterized by both analytical and spectroscopic methods, in a view ...

Schiff bases and their metal complexes are very important in medicinal and pharmaceutical fields because of their wide spectrum of biological activities. Transition metal complexes derived from the Schiff base ligands with biological activity have been widely studied. A series of Ni (II) complexes were prepared by the reaction of salicyldimine with Nickel Oxide at room temperature. The chemical...

Different Schemes for the synthesis of Schiff bases have been discussed. Solvent free synthesis by microwave irradiation technique is observed to be rapid, more efficient and more economical and at the same time may play a pivotal role in the progress of Schiff base synthesis. Mechanism for the synthesis of Schiff bases at controlled pH range has been studied. Biological functions of metal comp...

Benzoylpyridine and nitro benzoic acid hydrazides were used to examine novel Schiff base Co(II), Mn(II), Fe(II), Cu(II) complexes. Elemental analysis, molar conductance, magnetic measurements other methods that like FT-IR, UV–Vis 1H NMR studies have been deduce the nature of bonding structure these These revealed Fe(II) coordinated by four donor atoms in all Free radical scavenging activity was...

The Complexes of the type ML2 and M′L [where M= Cu(II), Co(II), Ni(II) and Mn(II); M′= Zn(II), Cd(II) and Hg(II)] with the Schiff base ligand (HMeOQMAMQ) L=3-[(2-hydroxy-6-methoxyquinolin-3-ylmethylene)amino]-2-methyl-3H-quinazoline-4-one, have been synthesized. Their characterizations have been done by elemental analysis, conductance data, magnetic susceptibility measurements, H NMR, electroni...
