The title complex, [Cu(C(18)H(18)N(2)O(6))], was synthesized by the reaction of copper(II) acetate mono-hydrate with the ligand 4,4'-dimeth-oxy-2,2'-[ethyl-enedioxy-bis(nitrilo-methyl-idyne)]diphenol (H(2)L). The Cu atom is coordinated by two O atoms and two N atoms of the L(2-) unit. A bridged dimer is formed through inter-molecular Cu⋯O inter-actions [Cu⋯O = 1.9408 (15) Å], creating a distort...

The title complex, [Cu(2)I(2)(C(10)H(11)N(3)O(2)S)(2)(C(18)H(15)P)(2)], is a centrosymmetric sulfur-bridged dimer of Cu(I) with PPh(3) and iodine. The Cu(I) atom shows a distorted tetra-hedral geometry, with bite angles ranging from 98.61 (2) to 120.16 (3)°. The intra-molecular Cu⋯Cu distance is 2.8228 (12) Å. The thio-semicarbazone ligand is coordinated only through the S atom. In the crystal,...

In the title coordination polymer, [Cu(2)I(2)(C(14)H(14)N(4))(C(18)H(15)P)(2)](n), the Cu(I) atom is coordinated by two I atoms, one P atom and one N atom in a fairly regular tetra-hedral arrangement. A crystallographic inversion centre generates a Cu(2)I(2) diamond with a Cu-Cu separation of 3.0120 (5) Å. The complete N,N'-(1-pyridin-4-yl-ethethyl-idene)-hydrazine mol-ecule is also generated b...

The title complex, [Cu(2)(C(4)H(5)O(2))(2)(C(12)H(8)N(2))(2)(H(2)O)(2)](NO(3))(2)·2H(2)O, contains a dimeric [Cu(2)(C(4)H(5)O(2))(2)(C(12)H(8)N(2))(2)(H(2)O)(2)](2+) dication with two five-coordinated Cu(II) ions linked by two methacrylate ions in a syn-syn bridging arrangement. The dication possesses pseudo-twofold rotational symmetry. The penta-coordination of each Cu(II) ion has a distorted ...

Chronic Cu toxicity was evaluated in the euryhaline copepod Acartia tonsa. Male and female copepods were exposed (6 d) separately to different combinations of Cu concentration and water salinity (5, 15, and 30 ppt) using different routes of exposure (waterborne, waterborne plus dietborne, and dietborne). After exposure, groups of one male and three female copepods were allowed to reproduce for ...

The title dinuclear copper complex, [Cu(2)(C(15)H(15)N(6)O)Cl(2)(CH(3)OH)(2)]ClO(4), was prepared by the reaction of copper(II) chloride with bis-[1-(2-pyrid-yl)ethyl-idene]carbonohydrazide in the presence of sodium perchlorate in a methanol solution. It features a mono-deprotonated bis-tridentate ligand, which coordinates to two independent Cu(II) ions, one of which is coordinated by pyridyl N...

Paramagnetic relaxation enhancements (PREs) are a rich source of structural information in protein solid-state NMR spectroscopy. Here we demonstrate that PRE measurements in natively diamagnetic proteins are facilitated by a thiol-reactive compact, cyclen-based, high-affinity Cu(2+) binding tag, 1-[2-(pyridin-2-yldisulfanyl)ethyl]-1,4,7,10-tetraazacyclododecane (TETAC), that overcomes the key s...

limited water resources, especially in iran, require most effective method of water use to avoid losses. one of the important parameters in irrigation is water distribution uniformity coefficient (cu) in sprinkler irrigation. cu in every irrigation depends on pressure heads (p), riser height (rh), distance between sprinklers on lateral pipes (sl), and the distance between lateral pipes (sm). th...

although cu and fe are immiscible under equilibrium conditions, they can form supersaturated solid solutions by mechanical alloying. in this paper, nano-structured of the metastable cu-fe phase containing 10, 15, 20 and 25% wt fe were synthesized by intensive ball milling for 15h, in order to achieve a solid solution of fe in cu. the phase composition, dissolution of the fe atoms into the cu ma...

To examine the effects of cattle breed on the clearance rate of an injectable mineral product, 10 Angus and 10 Simmental steers were blocked by breed and initial BW (332 ± 33 kg) and injected with either Multimin 90 (MM) or sterilized saline (CON) at a dose of 1 mL/45 kg BW. Multimin 90 contains 15 mg Cu/mL (as Cu disodium EDTA), 60 mg Zn/mL (as Zn disodium EDTA), 10 mg Mn/mL (as Mn disodium ED...
