Given the key role of Zn in many physiological functions, optimal Zn status could be a predictive parameter of successful ageing. However, the benefit of Zn supplementation is still a matter of debate since Zn supplementation has been reported to be associated with the alteration of Cu status and lipid metabolism. As part of the Zenith Project, the present study aimed to investigate, in free-li...

The title compound, Na[Cu(en)2][Cu(CN)4], where en represents ethyl-enedi-amine, NH2CH2CH2NH2, crystallizes as a salt with two distinct cations, Na(+) and [Cu(II)en2](2+), and discrete [Cu(I)(CN)4](3-) anions. The anion geometry is tetra-hedral, with angles at the copper atom ranging from 105.0 (1) to 115.4 (1)°. The Cu-C distances are in the range 1.976 (3) to 1.993 (3) Å. The divalent copper ...

In the title compound, [Cu(NCS)(C3H9PS)] n , the thio-cyanate ions bind the Cu(I) atoms covalently, forming infinite -Cu-SCN-Cu- chains parallel to the a axis. Each Cu(I) atom is also coordinated to a tri-methyl-phosphine sulfide group via a Cu-S bond. Two crystallographically independent chains propagate in opposite directions, and are held together in a ribbon arrangement by long bonds betwee...

Pb2Cu3B4O11 crystallizes in the monoclinic space group P2/n (No. 13) with a = 6.8016(15) A, b = 4.7123(10) A, c = 14.614(3) A, beta = 97.089(3) degrees, and Z = 2. The crystal structure consists of infinite [Cu3O8]10- zigzag chains of alternating dimers and monomers. The magnetic susceptibility and specific heat capacity show spin-gap and Curie-Weiss behaviors that can be explained by a model o...

The N-heterocyclic ligand in the title compound, [Cu(NCS)(C(15)H(13)N(5)S(2))](n), coordinates to the Cu(I) atom through its pyridine N-donor site, and adjacent metal atoms are bridged by the thio-cyanate ion, forming a helical chain along the b axis. The geometry of the metal atom is tetra-hedral owing to a somewhat long intra-molecular Cu-S inter-action of 2.5621 (9) Å.

The title complex, [Cu(2)(C(15)H(12)N(3)O(2)S)(2)(NO(3))(CH(3)OH)]NO(3), has two Cu(II) centres coordinated by two deprotonated 2-[(benzothia-zol-2-yl)hydrazonometh-yl]-6-methoxy-phenol ligands, a methanol mol-ecule and a nitrate ion. Both Cu(II) centres are penta-coordinated in a distorted square-pyramidal fashion. The crystal structure is stabilized by N-H⋯O and O-H⋯O hydrogen bonds.

Pollution induced community tolerance (PICT) to Cu(2+), and co-tolerance to nanoparticulate Cu, ionic silver (Ag(+)), and vancomycin were measured in field soils treated with Cu(2+) 15 years previously. EC50 values were determined using substrate induced respiration and correlations made against soil physicochemical properties, microbial community structure, physiological status (qCO2; metaboli...

Reaction of 4'-phenyl-2,2':6',2''-terpyridine (phtpy), copper acetate hydrate and ammonium thio-cyanate under solvothermal conditions led to the formation of the title compound, {[Cu(C(21)H(15)N(3))(2)][Cu(2)(NCS)(4)]}(n). The structure is composed of discrete [Cu(phtpy)(2)](2+) cations and polymeric anionic {[Cu(SCN)(2)](-)} chains propagating along [010]. The central Cu(2+) ion in the cation ...

A neutral W/S/Cu cluster, [Cu(3)WIS(4)(C(15)H(17)P)(3)], was formed by the reaction of tetra-thio-tungstate(VI), CuI and diphenyl-propyl-phosphine (dpp) in dimethyl-formamide. The title compound exhibits a neutral half-open cubane-like skeleton, with Cu-I bonds of 2.8056 (8) and 2.9008 (8) Å, and one Cu⋯I short contact of 3.1722 (6) Å. The W atom exhibits a tetra-hedral coordination geometry th...
