In this paper, nickel oxide (NiO) nanoparticles have been prepared by solid state thermal decomposition of an acyclic nickel(II) complex (1,2-bis(2-formyl-3-methoxyphenyl)propane)nickel(II) chloride, [NiL]Cl2, in an electrical furnace at optimal temperature, 450 ºC for 3.5 h. The nickel(II) complex is obtained via solid state synthesis using nickel(II) chloride and tetradentate O4 acyclic ligan...

This study describes the effects of the substituents on electrochemical behavior and antioxidant activity of the three tetradentate Schiff bases, containing ethane-1,2- diamine, propane-1,3- diamine and butan-1,4- diamine as the amine part and salicylaldehyde, and corresponding Cd(II) complexes. Cyclic voltammograms of these compounds were recorded in dimethylsulfoxide and 0.1 M sodium perchlor...

Two dinuclear copper(II) thioether-oxime complexes ([Cu(DtdoH)]2(ClO4)2 and [Cu(DtudH)]2(ClO4)2 Æ 2CH3OH) have been synthesized. [Cu(DtdoH)]2(ClO4)2 reacted with excess BF3 Æ OEt2 to yield [Cu(Thyclops)]ClO4, a BF2 þ-macrocyclized di-oxime. [Cu(DtdoH)]2(ClO4)2 and [Cu(DtudH)]2(ClO4)2 Æ 2CH3OH are the first representatives of copper(II) thioether oximes which exhibit the classical out-of-plane o...

The reaction of organic molecules mediated by a metal center (template synthesis) can result in final connectivity that may differ from the one obtained absence metal. condensation carbonyl fragments with primary amines form C=N iminic bonds, so-called Schiff bases, which act as ligands for templating means lone pair on nitrogen atom. This review focuses template methods between compound (mainl...

Four Schiff bases (H2L1 to H2L4) were synthesized by the condensation of o-aminophenol and unsaturated diketones (1,5-diarylpent-4-ene-1,3- -diones). Analytical, IR, 1H-NMR mass spectral data revealed their existence in imine?enamine form. Dibasic tetradentate coordination ML complexes (M = Cu(II), Ni(II), Co(II), Zn(II), Cd(II), Hg(II)) was established based on physical, analytical data. The f...
