The crystal structure of the title compound, [Cu(C(11)H(19)N(2)P)(2)]PF(6), is composed of discrete [Cu(PN-iPr)(2)](+) cations [PN-iPr is 2-(diisopropyl-phosphanyl-amino)-pyridine] and PF(6) (-) anions. The Cu(I) atom is bis-chelated by two independent PN-iPr ligands. It has a distorted tetra-hedral coordination by two P atoms [Cu-P = 2.2277 (4) and 2.2257 (4) Å] and two pyridine N atoms [Cu-N ...

The title compound, [Cu(2)(CH(3)CO(2))(4)(C(7)H(5)NS)(2)] or [(C(7)H(5)NS)Cu](2)(μ-O(2)CCH(3))(4), crystallizes with one mol-ecule per unit cell. The coordination number of copper is six with four basal O atoms, one axial N atom and one axial Cu atom. Four acetate ligands act as bidentate linker and connect two Cu atoms, with a crystallographic inversion center located at the mid-point of the C...

The title compound, {(C(6)H(16)NO)[Cu(2)(CH(3)COO)(5)]·CH(2)Cl(2)}(n), consists of acetate-bridged Cu(2)(CH(3)COO)(4) units that are connected via another acetate anion at each terminus to form infinite anionic [{Cu(2)(CH(3)COO)(4)}(CH(3)COO)](n) chains along [100]. The connecting acetate is hydrogen bonded to the dieth-yl(2-hydroxy-ethyl)ammonium cation, and the dichloro-methane solvent mol-ec...

The paddlewheel-type centrosymmetric dinuclear title complex, [Cu(2)(C(7)H(5)O(2))(4)(C(8)H(6)N(2))(2)], contains four bridging benzoate groups and two terminal quinoxaline ligands. The octa-hedral coordination around each Cu atom, with four O atoms in the equatorial plane, is completed by an N atom of a quinoxaline mol-ecule [Cu-N = 2.2465 (18) Å] and by the second Cu atom [Cu⋯Cu = 2.668 (5) Å...

The objective of this study was to investigate the effect of supplemental tribasic copper chloride (Cu(2)(OH(3))Cl; TBCC) vs. Cu sulfate (CuSO(4)) on Cu status and voluntary forage DMI in growing heifers. Two 90-d experiments were conducted using 48 non-pregnant, crossbred heifers (24 heifers/experiment; 355 +/- 10.7 and 309 +/- 9.9 kg for Exp. 1 and 2, respectively). In each experiment, 3 supp...

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 ...

The physiologically occurring copper-glutathione complex, [Cu(I)-[GSH](2)], has the ability to react continually with oxygen, generating superoxide anions (O(2) (∙-)). We addressed here the effects that superoxide removal has on the redox state of Cu(I) and GSH present in such complex and assessed the formation of Cu(II)-GSSG as a final oxidation product. In addition, we investigated the potent...

We exploited a solution-based route for preparation of Cu, Cu(2)O, Cu(3)N, and Cu(2)S nanocrystals, that is, direct thermal decomposition of copper salts (Cu(NO(3))(2), CuSO(4)) in octadecylamine (ODA) solvent, which is a novel and ingenious chemical process.

Four binuclear complexes [Cu(dptsc)Cl]2 Æ 3H2O (1), [Cu(dptsc)Br]2 (2), [Cu(dptsc)(l-N3)]2 (3) and [Cu(dptsc)(NO3)]2 Æ H2O (4) (where Hdptsc = di-2-pyridyl ketone N(4)-methyl, N(4)-phenylthiosemicarbazone) have been synthesized and physicochemically characterized. Each Cu(II) atom in the monomeric unit exists in a penta-coordinate environment. The molecular structures of [Cu(dptsc)Br]2 and [Cu(...
