The crystal structure of the title complex, [Cu(2)(C(15)H(10)Cl(2)N(2)O(2))(2)(C(5)H(5)N)(2)], features centrosymmetric dimers. The Cu(II) ion is penta-coordinated in a quadratic pyramidal mode. The quadratic plane is formed by the O,O',N-tridentate ligand and a pyridine mol-ecule. The fifth coordination site is occupied by the O atom of another ligand showing a significantly longer Cu-O bond.

Inorganic copper is used as a broad-spectrum fungicide and bacteriocide on a variety of agricultural crops. After application, the copper residue typically accumulates in the upper 15 cm of soil. Data from the California Pesticide Use Reports were used to estimate the augmentation of copper in the soil that resulted from pesticide applications for the six years from 1993 to 1998 on 12 crops tha...

The simultaneous decomplexation of Cu-EDTA and electrodeposition recovery of Cu(2+) ions was attempted in a photoelectrocatalytic (PEC) system using TiO2/Ti as the anode and stainless steel as the cathode. At a current density of 0.5 mA/cm(2), removal efficiencies of 0.05 mM Cu-EDTA by photocatalysis, electrooxidation, and PEC processes were determined to be 15, 43, and 72% at 3 h, respectively...

Despite widespread use and prospective biomedical applications of copper nanoparticles (Cu NPs), their biosafety issues and kinetics remain unclear. Thus, the aim of this study was to compare the detailed in vivo toxicity of Cu NPs and cupric ions (CuCl2; Cu ions) after a single oral dose. We determined the physicochemical characteristics of Cu NPs, including morphology, hydrodynamic size, zeta...

The aim of this paper is to evaluate at a histopathological level the effect of the most commonly used copper (Cu) supplementation (15 mg/kg dry matter (DM)) in the liver of intensively reared beef cattle. This was done by a histochemistry evaluation of (i) the antioxidant capacity in the liver - by the determination of metallothioneins (MT) and superoxide dismutase (SOD) expression - as well a...

In the title compound, [Cu(C(17)H(15)ClN(2)O(5))(C(5)H(5)N)], the Cu(II) atom is coordinated by one N atom and two O atoms from an anionic salicyl-aldehyde benzoyl-hydrazone ligand and one pyridine N atom in a distorted square-planar geometry. The bonds displays the usual elongation with mean Cu-O and Cu-N bond lengths of 1.926 and 1.976 Å, respectively. The pyridine ring makes dihedral angles ...

Hierarchical structure of copper nanowires (Cu NWs) was formed by using simple solution process through hydrothermal approach, with an average length and diameter of 6 ± 2 μm and 120±15 nm respectively. The size and morphology of Cu NW was dependent on the reaction time. An extinction peak was observed at 560 nm indicate the possibility of Cu NW plasmonic effect. The absorption spectrum shows i...

X-band EPR spectra of imidazol ate-bridgcd [(glyval)Cu-im-Cu-(glyvai)]Na and [(glyval)Cu-im-Zn(glyvai)]Na,where glyval = glycylvaline, im = imidozolate ion, are described.The EPR and electronic spectra of related mononuclear complexes viz., aquoglycylvalinato copper(ll) and imidazole glycylvalinato copper(ll) are also described. A pH dependent EPR study of frozen 50% aqueous DMSO solution of [(...

In the title compound, [Cu(C(18)H(15)P)(2)(H(2)O)]BF(4), the Cu(I) atom is coordinated by two P atoms from triphenyl-phosphine ligands and one water mol-ecule in a distorted trigonal geometry. In the BF(4) (-) anion, three F atoms are disordered over two sites around the B-F bond, the site-occupancy ratio being 0.67 (6):0.33 (6). The Cu⋯F distance of 2.602 (5) Å between the Cu atom and the orde...

In the title mononuclear complex, [Cu(C(9)H(9)O(3))(2)(H(2)O)(2)], the Cu(II) ion, located on an inversion center, is hexa-coordinated by four O atoms from two benzyl-oxyacetate ligands [Cu-O = 1.9420 (14) and 2.2922 (14) Å] and two water mol-ecules [Cu-O = 2.0157 (15) Å] in a distorted octa-hedral geometry. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into...
