new hetero-binuclear hg-cu schiff base complexes were prepared by reaction of 2,2'-[1,1'-(2,2-‎dimethylpropane-1,3-diyldinitrilo)-diethyldyne]diphenolato}copper(ii) (cul1) and 6,6'-x-2,2'-[(2,2-‎dimethylpropane-1,3-diyl)bis(nitrilomethanylylidene)]diphenolato copper(ii) [(x = ethoxy (cul2) and ‎methoxy (cul3)], with hgcl2 to give [cu(l1)hgcl2] (1), [cu(l2)hgcl2] (2), and [cu(l3)hgcl2] (3), ‎res...

The segmental ligand 2-[6-(N,N-diethylcarbamoyl)pyridin-2-yl]-1,1'-dimethyl-5,5'-methylene-2'-(6-methylpyridine-2-yl)bis[1H-benzimidazole] (L3) reacts with a stoichiometric mixture of LnIII (Ln = La, Eu, Gd) and M(II) (M = Zn, Fe) in acetonitrile to produce selectively the heterodimetallic triple-stranded helicates (HHH)-[LnM(L3)3]5+. In these complexes, M(II) is pseudooctahedrally coordinated ...

The massive worldwide use of antibiotics leads to water pollution and increasing microbial resistance. Hence, the removal antibiotic residues is a key issue in remediation. Here, we report solar light-assisted oxidative degradation ciprofloxacin (CPF), using H2O2 aqueous solution, catalyzed by iron(III) chelated cross-linked chitosan (FeIII-CS-GLA) immobilized on glass plate. FeIII-CS-GLA catal...

This article reviews investigations on the formation of inhomogeneous ferrous (FeII) and ferric (FeIII) oxides in aqueous solution. These globally abundant materials are important extensive fields research including corrosion steels, mineralogy, environmental remediation, biochemistry. Iron polycations consisting FeII FeIII ions bridged by hydroxyl groups oxyanions. Solution conditions such as ...

This paper reports on a series of five chiral Schiff base push-pull compounds derived from enantiomerically pure (1R,2R)-(?)-1,2-diaminocyclohexane. The NiII, CuII, ZnII and PdII complexes supported by ferrocene-containing unsymmetrically-substituted N2O2 quadridentate ligand were prepared via template reactions isolated in 74–87 % yields. A combination EA, IR, UV/vis 1H/13C{1H} NMR spectroscop...
