Catalytic behaviour of [Cu(en)2]2+ sorbed on zirconium molybdate in the decomposition of hydrogen peroxide

Zirconium molybdate has been used as a support on which [Cu(en)2]2+ has been sorbed. The catalytic activity has been studied via hydrogen peroxide decomposition at different temperatures, using different concentrations of hydrogen peroxide and different amounts of catalyst. A probable mechanism for the reaction is suggested on the basis of the kinetic data obtained.

The polynuclear complexes of iron(II,III) and copper(II) with cyanide as bridging ligand

Five novel complexes of the type [CuL2][Fe(CN)5NO]. xH2O (L = ethylenediamine (en), x = 0; L = o-phenanthroline (phen) or 2,2′-bipyridine (bpy), x = 2), [CuL2]3[Fe(CN)6]2. xH2O (L = bpy, x = 6; L = phen, x = 9) have been prepared and studied by elemental analyses, thermal analyses, IR and UV - vis. spectra and magnetic measurements. The structures are proposed with cyanide bridges between Fe(II) and Cu(II) (nitroprusside complexes) or between Fe(III) and Cu(II) (hexacyanoferrate(III) complexes). The temperature dependence of the magnetic susceptibility of the complex [Cu(bpy)2]3[Fe(CN)6]2. 6H2O was measured in the range 94.4 - 293.5 K but no exchange interaction was found. The product of the thermal decomposition of the complex [Cu(bpy)2]3[Fe(CN)6]2.6H 2O is a mixture of CuO and CuFe2O4, as determined by X-ray powder diffraction.

Determination of solution structures of binuclear copper(II) complexes

A simple and efficient method for the determination of solution structures of weakly coupled binuclear copper(II) complexes is described. The technique involves the combination of molecular mechanics and EPR spectroscopy and has been applied to the binuclear copper(II) complexes of 5,5′-bis(3,7-dehydro-3,7-diazanonane-4,6-dione-1,9-diamine) (L1), 5,5′-bis(3,7-diazanonane-1,9-diamine) (L2), and 5-methyl-5-nitro-3,7-diazanonanedioate (L3). The complexes [Cu2L1]·10H2O and [Cu2L2](ClO4)4 were also characterized by X-ray crystallography. [Cu2L1]·10H2O: space group P1; a = 7.669 (2), b = 8.757 (3), c = 10.596 (2) A?; α = 79.57 (3), β = 83.36 (2), γ = 89.17 (3)°. [Cu2L2](ClO4)4: space group P3221; a = 13.671 (2), b = 13.671 (2), c = 13.929 (2) A?. There is excellent agreement between the X-ray crystal structures and the structures predicted by molecular mechanics and EPR spectroscopy. Electrochemical properties of the binuclear complexes are also reported.

TEMPLATE REACTIONS OF FLUORINE-CONTAINING 1,3-DIKETONES WITH ETHYLENEDIAMINE

Depending on the nature of the dicarbonyl fragment, the reaction of fluorinated copper(II) bis(1,3-diketonates) with ethylenediamine and its monoprotonated salts under mild conditions gives N,N'-ethylenebis(aminovinyl ketones) and/or 1,4-diazepines.In excess ethylenediamine, copper(II) and nickel(II) N,N'-ethylenebis(aminovinyl ketonates) undergo cyclization to 1,4-diazepines.
