Tetraalkoxyaluminates of Nickel(II), Copper(II), and Copper(I)

Inorganic Chemistry, 2008
The syntheses and structural details of tetraisopropoxyaluminates and tetra-tert-butoxyaluminates of nickel(II), copper(I), and copper(II) are reported. Within the nickel series, either Ni[Al(OiPr)4]2.2HOiPr, with nickel(II) in a distorted octahedral oxygen environment, or Ni[Al(OiPr)4]2.py, with nickel(II) in a square-pyramidal O4N coordination sphere,

Copper(ii) fluorophosphates

Dalton Transactions, 2012
Eleven new copper fluorophosphate frameworks have been synthesised hydrothermally in a fluoride-rich medium, through the use of CuF(2) HPF(6) and monovalent metal fluorides as reactants. Products have been structurally characterised using single crystal X-ray diffraction.

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 ...
