As part of a programme to determine crystal structure in binary alloys in which one component is Cu, Ag, or Au and the other As, Sb, Bi, or P, the structure of alloys of Cu and Bi was examined and is here reported.doi:10.1080/14786443009461608...
Central to this system is the copper responsive CueR protein that regulates gene expression of copper defense proteins. The high metal sensitivity and selectivity of CueR and the structural basis of these traits have been previously studied. However, the mechanism by which CueR upregulates gene ...
these primitive cells by themselves (when isolated from the lattice) do not display the full symmetry of the particular system. They are unit cells, nevertheless, since when translated parallel to themselves by their translation vectors they fill all space and produce the original lattice. The exam...
Two new copper(I) complexes Cu(S2PiBu2)·(PMe3)3 (1) and Cu(S2PiBu2)·(PPh3)2 (2) have been synthesised and characterised by spectroscopic and X-ray crystallographic methods. Both compounds are monomers in the solid state where copper is four co-ordinate and the co-ordination geom...
Variation of the ground spin state in homo- and hetero-octanuclear copper(II) and nickel(II) double-star complexes with a meso-helicate-type metallacryptan... Homo- and heterometallic octanuclear complexes of formula Na₂{[Cu₂(mpba)₃][Cu(Me₅dien)]₆}-(ClO₄)₆·12H₂O...
Crystal structures of compounds 2, 3 and 5 have been solved. All these compounds crystallize in the triclinic system, space group P&onemacr;, with a = 7.3322(3) , b = 10.014(1) , c = 11.541(1) , alpha = 113.22(1) degrees, beta = 91.37(1) degrees, gamma = 94.51(1) degrees,...
spectra are interpreted in terms of a fluxional CuN2O4 chromophere in 5% copper-doped (1) and are compared with the corresponding copper-doped K2[Zn(OH2)6][SO4]2 system. The electronic properties of complex (2) and >50% copper-doped (1) suggest that the CuN2O4 chromophore has...
A thiocyanate bridged one-dimensional chain copper(II) complex, {[(232-tet)Cu(NCS)]-(C104)} n , where 232-tet = N,N'-bis(2-aminoethyl)-l,3-propanediamine, has been synthesised and its crystal structure determined at room temperature. This complex crystallises in the orthorhombic system...
The calculation is the lowest energy in a system of 80 vol.% solid –20 vol.% liquid at a contact angle of 20°. The liquid placement results in the minimum energy. Another low energy terminal configuration consists of a liquid sphere located inside the solid grains, and this is evident ...
Ternary compounds of the adamantine family, with general formula AIBIIIXVI2, crystallize in the chalcopyrite-type crystal structure (space group 𝐼4̲2𝑑I4¯2d) and belong to the tetragonal crystal system. In this crystal structure, each metal ion is tetrahedrally coordinated with four chalco...
