A new copper(II) complex with formulae of [Cu(buobb)(2)](pic)(2), where buobb stands for the ligand of 1,3-bis(1- butylbenzimidazol-2-yl)-2-oxopropane and pic represents 2,4,6-trinitrophenol, has been synthesized and characterized by elemental analyses, molar conductivity, IR, UV-Vis spectra measurements, and cyclic voltammetry. The crystal structure of the copper(II) complex has been determine...

In the title compound, [CuCl(2)(C(4)H(4)N(2)O)(H(2)O)], the Cu(II) cation is coordinated by two chloride anions, one pyrimidin-2-one N atom and one water mol-ecule, giving a slightly distorted square-planar geometry. In the crystal structure, the pyrimidin-2-one rings stack along the b axis, with an inter-planar distance of 3.306 Å, as do the copper coordination planes (inter-planar spacing = 2...

In the title compound, {[(C(2)H(5))(3)NH][Cu(2)(CH(3)COO)(5)]·C(4)H(8)O}(n), the two different Cu(II) atoms are coordinated in a pseudo-square-pyramidal environment by five O atoms from the acetate ligands. Neighbouring pairs of Cu(II) atoms are linked by four basally coordinating bridging acetate ligands as in the crystal structure of copper acetate monohydrate. The fifth, apically coordinatin...

In the title compound, [Cu(C6H9N2O2)2], the Cu(II) atom is located on an inversion center and has a square-planar environment. Two 2-(hy-droxy-imino)-cyclo-hexan-1-one oxim-ate monoanions chelate to the Cu(II) atom and the Cu-N distances are 1.920 (3) and 1.930 (3) Å. There are two short intra-molecular O-H⋯O hydrogen bonds between the ligands. The complex mol-ecules stack into columns extended...

The putative copper binding domain from the copper-transporting ATPase implicated in Wilson disease (ATP7B) has been expressed and purified as a fusion to glutathione S-transferase. Immobilized metal ion affinity chromatography revealed that the fusion protein is able to bind to columns charged with different transition metals with varying affinities as follows: Cu(II)>>Zn(II)>Ni(II)>Co(II). Th...

The title complex, [Cu(C(26)H(20)NO(2)P(2))(2)], contains a central Cu(II) atom surrounded by two homoleptic bidentate ligands, which form two five-membered chelate rings. The Cu atom binds to four O atoms, resulting in a four-coordinate square-planar complex. The asymmetric unit contains half of the complex, the other half being completed by inversion symmetry. The Cu-O bond lengths have simil...

In the title compound, {[Cu(C(7)H(8)N(4)S(4))(4)](ClO(4))(2)}(n), the Cu(II) atom, occupying a crystallographic inversion centre, is six-coordinated by six N atoms of three symmetry-related 2,2'-(propane-1,3-diyldithio)bis-(1,3,4-thia-diazole) (L) ligands in a slightly distorted octa-hedral geometry. The ligand L adopts two kinds of coordination modes in the crystal structure; one is a monodent...

BACKGROUND Ceriporia lacerata, a strain of white-rot fungus isolated from the litter of an invasive plant (Solidago canadensis) in China, was little known about its properties and utilization. In this work, the copper(II) biosorption characteristics of formaldehyde inactivated C. lacerata biomass were examined as a function of initial pH, initial copper(II) concentration and contact time, and t...
