Copper Complex-Assisted DNA Hybridization
Bioconjugate Chemistry, 20062,2'-Bipyridine (bpy) or 1,10-phenanthroline (phen) metal-binding domains were covalently attached to oligonucleotides, and the influence of metal ions on the hybridization of the conjugates was investigated. Metal-binding domains were attached to oligonucleotides at 3'- and 5'-terminal positions, thus placing them in juxtaposed positions after ...

FTIR Study of Glyphosate−Copper Complexes
Journal of Agricultural and Food Chemistry, 2002Complexes of the herbicide glyphosate (GPS) and the heavy metal Cu were studied by infrared spectroscopy under controlled pH, in order to know the mechanisms involved in the formation of these complexes. In CuGPS(-), the IR spectrum shows participation of the carboxylate and phosphonic moieties of the GPS molecule. The formation of the complex produces

Histidine-Copper (II) Complexes
Nature, 1959STABILITY constants are known for copper complexes of most of the naturally occurring α-amino-acids. However, although it is of considerable biochemical interest, the copper–histidine system has not been interpreted in detail. The system is anomalous, probably because, although the metal can co-ordinate to the amino, imidazole or carboxyl groups in ...

Abstract The preparation of a complex of CuCH3 with PPh3 is reported. Other copper (I) complexes are described from anhydrous copper (II) nitrate or copper (I) halides, CH3MgBr and PPh3 or from copper (I) halides and PPh3.

A Copper–Nitromalonamide Complex
Acta Crystallographica Section C Crystal Structure Communications, 1995Bis(2-nitromalonamide-O,O')copper(II), [Cu{O 2 NC(CONH 2 ) 2 } 2 ], is a neutral complex. The Cu atom is octahedrally coordinated to six O atoms from four ligands and is situated on a centre of symmetry. Each ligand coordinates to the Cu atom via relatively short bonds from the amide O atoms.

Copper complexes of tricyclohexylphosphine
Journal of Inorganic and Nuclear Chemistry, 1970Abstract The preparation of copper(I) complexes with tricyclohexylphosphine (PCy3) is reported. From i.r. spectra in the range 4000-200 cm−1, mass spectra, molecular weight measurements and conductance measurements we suggest a trigonal configuration around copper in the complexes Cu(PCy3)2X with X = Cl or Br and CuPCy3X with X = Cl, Br or I.

THE criticism recently levelled by Bayley and Rose1 at our findings concerning a copper-cellulose complex in wood implies that they have neither appreciated the weight of our evidence nor have they realized the complexity of the problems involved. We recommend that they should see all our papers on this matter2–6.

In order to investigate the exchange between copper complexes (Cu centers) in silicon crystal, the change of the photoluminescence (PL) intensity of the Cu center (Cu PL center; no-phonon peak: 1.014 eV) with annealing time was measured for p-type float-zone grown silicon crystals diffused with various concentrations of Cu at 700 °C followed by rapid ...

Triethanolamine complexes of copper
Inorganica Chimica Acta, 1999Abstract A simple benchtop synthesis of the deep blue tetrameric compound [Cu{N(CH2CH2O)3H}]4 prepared from CuSO4·5H2O and triethanolamine is presented. The compound has been characterized in three different crystalline modifications which vary due to the presence of different lattice solvents that include THF, Et2O and H2O. The compound dissolves in
