the mononuclear complex [cu(l)(ch3cn)(pph3)]clo4, (1), (l= 2,5-diphenyl-3,4-bis(2-pyridyl)cyclopenta-2,4-dien-1-one), has been synthesized and investigated by elemental analysis, ir, 1h nmr, uv-vis spectroscopic methods and x-ray diffraction. the complex crystallizes in the non-centrosymmetric space group p212121 in accord with the asymmetric (atropisomer) cu centre. its coordination polyhedron...

Copper(II)  complex  [Cu(dmbt)2(H2O)](ClO4)2 (1)  was  prepared  from  the  reaction  of  copper(II) perchlorate  hexahydrate  with  2,2'-dimethyl-4,4'-bithiazole  (dmbt)  ligand  in  methanol  at  ambient temperature. The complex was quantitatively and qualitatively characterized by elemental analysis, absorption  and  infrared  spectrometries.  Complex  [Cu(DMSO)5](ClO4)2 (2)  was  also  synt...

it is known that a stochastic dierential equation (sde) induces two probabilisticobjects, namely a diusion process and a stochastic ow. while the diusion process isdetermined by the innitesimal mean and variance given by the coecients of the sde,this is not the case for the stochastic ow induced by the sde. in order to characterize thestochastic ow uniquely the innitesimal covariance give...

background: soil serves as a major reservoir for contaminants as it can bind to various chemicals. the aim of this study was to evaluate the levels of some metals (cd, cu, fe and v) in soil samples collected from different stations of ahvaz industrial complex ii to determine the natural and anthropogenic contribution of metal in the soil. methods: this was an experimental study that carried out...

The formation of Cu(II) complexes with two isomeric quinoline-containing scorpiand-type ligands has been studied. The ligands have a tetraazapyridinophane core appended with an ethylamino tail including 2-quinoline (L1) or 4-quinoline (L2) functionalities. Potentiometric studies indicate the formation of stable CuL(2+) species with both ligands, the L1 complex being 3-4 log units more stable th...

A new voltammetric sensor for determination of uric acid (UA) by Cuppercomplex- multiwalled carbon nanotube (Cu-complex-CNT) nanocomposite modifiedcarbon paste electrode (CPE) is reported. The electrocatalytic behavior of theCu-complex-CNT nanocomposite modified CPE was studied in pH 2.0 phosphatebuffer solution by chronoamperometry (CA) and cyclic voltammetry (CV) in th...

2-(Methylamino) pyridine (HMAP) reacts with MeLi in THF and generates the lithium salt (LiMAP). Further reaction of [Cu(TMEDS)2][CuCl2] (TMEDA=tetramethylethylenediamine) with one equivalent of this ligand in THF leads to the formation of a yellow dimeric Cu(I) complex, [Cu(MAP)]2. Analytical data, molecular weight, and magnetic susceptibility measurements, ...

Suspensions of bimetallic nanoparticles (NPs) of Ru and Cu have been synthesized by simultaneous decomposition of two organometallic compounds in an ionic liquid. These suspensions have been characterized by Anomalous Small-Angle X-ray Scattering (ASAXS) at energies slightly below the Ru K-edge. It is found that the NPs adopt a Ru-core, a Cu-shell structure, with a constant Ru core diameter of ...
