3-Dialkylaminomethyl substituted salicylaldoximes are efficient metal salt extractants, and, in contrast to related "salen"-based reagents, are sufficiently stable to acid hydrolysis to allow commercial application in base metal recovery. Crystal structures show that metal salts are bound by a zwitterionic form of the reagents, with copper(II) nitrate, tetrafluoroborate and trifluoroacetate for...

Schiff bases and their metal complexes in the mixtures of ionic liquid (IL) + organic solvent have shown great potential in attractive oxidation catalytic processes. The efficiency of such a process is strongly dependent on the various molecular interactions occurring between components. Thermodynamic properties of these systems can provide valuable information about structural interactions. Th...

three new rimantadine schiff bases (rsbs) were prepared, and then the interaction of rsbs with bovine serum albumin (bsa) was investigated using fluorescence, synchronous fluorescence, uv-vis absorption spectroscopy under physiological conditions. the results showed that the three rsbs effectively quenched the intrinsic fluorescence of bsa via static quenching. binding constant (ka), number of ...

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...

in this paper, plate-like nio nanoparticles were prepared by one-pot solid-state thermal decomposition of nickel (ii) schiff base complex as new precursor. first, the nickel (ii) schiff base precursor was prepared by solid-state grinding using nickel (ii) nitrate hexahydrate, ni(no3)2∙6h2o, and the schiff base ligand n,n′-bis-(salicylidene) benzene-1,4-diamine) for 30 min without using any solv...

That phosphonium-type ionic liquids (ILs) can be used for preparation of novel solid-phase extractants has been shown. The conditions of IL immobilization on the different matrices (polyacrilonitrile, Amberlite XAD-7, hyper cross-linked polystyrene, and multi-walled carbon nanotubes) were determined. The solid-phase extraction of Pt(IV) from 1-2 M HCl and Pu(IV) from 3 M HNO(3) has been investi...

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...

Oxovanadium(IV), manganese(II) and copper(II) complexes of a Schiff base ligand derived from 2,4-dihydroxyacetophenone and 1,2-diaminocyclohexane have been encapsulated in the nanocavity of zeolite-Y by flexible ligand method and characterized by metal analysis, IR spectroscopic studies and X-ray diffraction patterns. The encapsulated complexes abbreviated here as CuL-Y, MnL-Y and VOL-Y catalyz...

In the title compound, [Zn(NCS)(C(16)H(18)N(4))]ClO(4), the Zn(II) atom is five-coordinated by four N atoms of the Schiff base ligand N,N'-bis-[1-(2-pyrid-yl)ethyl-idene]ethane-1,2-diamine in the basal plane, and by the N atom of a thio-cyanate ligand at the apical position, forming a distorted square-pyramidal geometry. The r.m.s. deviation from a plane through the four N atoms of the Schiff b...
