Reduction of Copper(II) by Iron(II)

Journal of Environmental Quality, 2005
ABSTRACTLaboratory and field investigations have clearly demonstrated the important role of reduced iron (Fe(II)) in reductive transformations of first‐row transition metal species. However, interactions of Fe(II) and copper (Cu) are not clearly understood. This study examined the reduction of Cu(II) by Fe(II) in stirred‐batch experiments at pH 5.2 and

Homobinuclear Complexes of Copper(II) with Copper(II) Thiocarbohydrazones

Synthesis and Reactivity in Inorganic and Metal-Organic Chemistry, 1986
Abstract Copper(II) binuclear complexes of copper(II) thiocarbohydrazones were prepared by reacting copper(II) acetate with copper(II) thiocarbohydrazones in ethanol. All the complexes are bright green in colour and appear to be non-electrolytes in DMF. Elemental analyses conform to the 1:1 stoichiometry of the type CuL.Cu(OAc)2.

Synthesis, spectra and biomimetic properties of copper(II)–copper(II) and copper(II)–zinc(II) binuclear complexes with CuN5 chromophores

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2005
X-band electron spin resonance (ESR) and UV-vis spectra of a homobinuclear [(Bipy)2Cu-E-Im-Cu(Bipy)2](BF4)3 and a heterobinuclear [(Bipy)2Cu-E-Im-Zn(Bipy)2](BF4)3 complexes, E-Im=2-ethylimidazolate ion have been described as possible models for superoxide dismutase (SOD).

Synthesis and magnetic studies of oxalato-bridged copper(II)–chromium(III)–copper(II) and copper(II)–iron(III)–copper(II) heterotrinuclear complexes

Polyhedron, 2003
Abstract The strategy of “complex as ligand” allowed us to synthesize three new μ-oxalato-bridged heterotrinuclear complexes identified as [Cu2Cr(ox)3(Mephen)2]ClO4 (1), [Cu2Fe(ox)3(Mephen)2]ClO4 (2) and [Cu2Fe(ox)3(Me2bpy)2]ClO4 (3), where ox represents the oxalato dianions; Mephen and Me2bpy stand for 5-methyl-1,10-phenanthroline and 4,4′-dimethyl ...

A hexaicosametallic copper(ii) phosphonate

Dalton Transactions, 2013
Structure and characterization of [Cu26{2,3,5,6-(Me)4C6H-CH2-PO3}18(μ2-OH)4(μ3-OH)6(μ4-Cl)6(μ-OH2)2(OH2)2(MeCN)4]·6MeCN·15H2O (1) is reported. Complex 1 is the largest discrete molecular homometallic transition metal phosphonate assembly. Remarkably, this gigantic molecular phosphonate has been prepared at room temperature using a normal solution ...

A hexadecameric copper(II) phosphonate

Dalton Transactions, 2009
The first example of a hexadecanuclear copper(II) phosphonate containing pyrazole, hydroxide and acetate ancillary ligands has been assembled in a reaction involving copper(II) nitrate, pyrazole, t-butylphosphonic acid and triethylamine.

Antilupus activity of copper (II)

Experimental pathology, 1985
Collagen-like syndrome was induced in rats by oral hydralazine administration during 5 months. After 4 months, a subgroup of rats was shifted from the standard diet to the diet supplemented with copper (II) (60 micrograms of copper per g of pellet) as copper sulphate. A decreased serum copper concentration was noted, LE cells were observed in the blood

(−)-Sparteine copper(II) diacetate

Acta Crystallographica Section C Crystal Structure Communications, 2000
The chiral nitrogen-chelating alkaloid (−)-sparteine acts as a bidentate ligand, reacting with copper(II) acetate in ethanol to form the title complex, [Cu(CH3COO)2(C15H26N2)], with the two acetate groups occupying the remaining coordination sites in a monodentate fashion to produce a distorted four-coordinate tetrahedral structure.
