Die Berechnung von Kriterien für die Abscheidung reiner Phasen binärer Systeme beim chemischen Transport und der Transport im System Cu-O

A thermodynamical analysing method is described of the deposition of binary solids AB_x, which specially takes into account the influence of the coexistence equilibria in the A—B-system. This analysis is applicated to the Cu—O system. It permits to calculate the conditions, under which Cu₂O is deposited without deposition of any other phases. The deposition of cuprous oxide by CTR-techniques is investigated using hydrogen halides as transport media. The experiments result in the growth of Cu₂O-monocrystals (2 × 2 × 2 mm) only if HCl is used as transport medium. Using HI the simultaneous deposition of Cu₂O and Cu is observed.     

Syntheses and Crystal Structures of Two CuII Coordination Isomers [Cu(pmt)2] · 4H2O (1) and {[Cu(pmt)2] · 2H2O} n (2)

Abstract  A pair of Cu^II coordination isomers [Cu(pmt)₂] · 4H₂O (1) and {[Cu(pmt)₂] · 2H₂O} _n (2) [Hpmt = 2-(2-pyridylmethylamino) ethanesulfonic acid] have been prepared by reaction of the same proportion CuCl₂ · 2H₂O and Hpmt but with different experimental methods in water–methanol mixed solution, and were characterized by X-ray diffraction, elemental analysis, IR spectrum. X-ray analysis indicates that complex (1) is a mononuclear complex in which two deprotonated pmt ligands coordinate in a facial tridentate arrangement about the Cu^II atom. While complex (2) is a coordination polymer, in which four N atoms of pmt ligands coordinate to one Cu^II atom but its sulfonate O atoms bond to adjacent Cu^II atom. Thus 12-membered rings (–Cu–N–C–C–S–O–)₂ are obtained between two neighbouring Cu^II atoms and they connect one another to form this new polymer.

Synthesis and crystal structure of a phthalate-bridged copper(II) complex {[Cu(L)(Phen)(H<Subscript>2</Subscript>O)]⋅H<Subscript>2</Subscript>O}<Subscript><Emphasis Type="Italic">n</Emphasis></Subscript>

A phthalate-bridged copper(II) complex {[Cu(phth)(Phen)(H₂O)] H₂O}_n (H₂phth: phthalic acid, Phen: 1,10-phenanthroline) has been synthesized by the reaction of CuCl₂ and phthalic acid in the presence of 1,10-phenanthroline in aqueous solution. The crystal structure of the complex has been determined by X-ray diffraction analysis to be orthorhombic, with the centrosymmetric space group Pbcm, where a = 11.6652(3) Å, b = 11.1709(3) Å, c = 14.0532(4) Å, V = 1831.28(9) ų, Z = 4. The L^2– (the acid radical of H₂phth) ion is coordinated to the Cu²⁺ ion as a monodentate ligand. Each L^2– ion bridges two adjacent Cu²⁺ ions with its two oxygen atoms from two carboxylic groups to form a one-dimensional zigzag chain. The coordination water and uncoordinated carboxylic oxygen atoms from neighboring chains are linked through hydrogen bonds to form a two-dimensional structure. There is a weak interaction between the coordination water molecule and the Cu²⁺ ion in the neighboring chain.

Synthesis and crystallographic characterization of a six coordinate Cu(II) complex based on hexamethylenetetramine ligand

The title compound, Cu(H₂O)₆]Cl₂.2{(CH₂)₆N₄}.4H₂O ( 1 ), has been prepared under mild hydrothermal conditions. Each Cu^II atom, located on a centre of symmetry, is coordinated by six water molecules in distorted octahedral coordination geometry. The hexamethylenetetramine molecule does not coordinate to the Cu atom but links with the Cu complex via three O—H…N hydrogen bonds. The remaining N atom of the hexamethylenetetramine is hydrogen‐bonded to the solvent water molecule. In the crystal structure, intermolecular O—H…O, O—H…N and O—H…Cl hydrogen bonds link the components into a three‐dimensional network. (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)     

Effect of Ni-addition on the crystallization behavior and the oxidation resistance of Zr-based metallic glasses below the crystallization temperature

The crystallization behavior of Zr_65.0Al_7.5Ni_10.0Cu_17.5 metallic glasses by addition of Ni with 753 K annealing treatment and its effect on the oxidation resistance around the supercooled liquid region at 663 K were studied. By annealing at 753 K, the nanocrystalline phase of bct-Zr₂Cu precipitates was observed in the Zr_65.0Al_7.5Cu_27.5 specimen, while microstructures consisting of finer nanocrystalline bct-Zr₂Cu, fcc-Zr₂Ni and Zr₆Al₂Ni formed in the Zr_65.0Al_7.5Ni_10.0Cu_17.5 specimen. The oxidation resistance of the melt-spun Zr_65.0Al_7.5Ni_10.0Cu_17.5 specimen was improved by addition of Ni, which is evidenced by less mass gain and thin oxide scale. The microstructural refinement by the formation of numerous nanocrystalline phases of bct-Zr₂Cu, fcc-Zr₂Ni and Zr₆Al₂Ni from the matrix resulted in an improvement of the oxidation resistance, whereas a relative coarse nanocrystalline phase consisting of bct-Zr₂Cu exhibited fast oxidation along grain boundaries. Although the oxide species for both specimens were composed of a large amount of CuO/Cu₂O, some tetragonal and monoclinic-ZrO₂ as well as a minor amount of the oxide state of Cu³⁺, the amount of oxides especially for ZrO₂ in the Zr_65.0Al_7.5Ni_10.0Cu_17.5 specimen was lower, which was probably due to suppressed oxygen diffusion in ZrO₂.     

Crystal and molecular structure of di-μ-chlorobis[2-[[[(2-hydroxy-1-naphthyl)methyl]-imino]ethanolato]N,O,O′]di-copper(II) dihydrate

The crystal structure of the title compound has been determined from three-dimensional, single crystal X-ray diffraction data. [Cu₂Cl₂(C₁₃H₁₂NO₂)₂]·2H₂O crystallizes in the orthorhombic space group P2₁2₁2₁ with lattice constants,a=11.866(2),b=13.555(3),c=17.380(3) Å. Final full-matrix least-squares refinement of 3735 unique reflections yieldedR=0.054. The structure consists of dimeric C₂₆H₂₄Cl₂Cu₂N₂O₄ molecules and water molecules connected with the dimeric molecules by a hydrogen bond system. Both of the copper(II) centers are five-coordinated by twotrans oxygen atoms and one nitrogen atom from one ligand molecule and two chloride ions. The geometry at each copper(II) center is best described as distorted tetragonal pyramidal. The apical Cu1–Cl2 and Cu2–C11 distances are 2.747(2) and 2.938(3)Å, respectively. The Cu...Cu separation is 3.496(1)Å. The comparison with previously reported crystal structure of [Cu₂Cl₂ (C₁₃H₁₂NO₂)₂]·1/2H₂O is given.     

Diamagnetism and some peculiarities of interatomic interactions in Cu2Sb

Results are reported for magnetic susceptibility measurements of high purity Cu₂Sb which characterize it as a diamagnetic. The observed anomalies of magnetic susceptibility, electrical resistivity and linear expansion coefficient in the neighbourhood of 370 K verify the existence of a phase transition of nonmagnetic origin in this temperature range. The analysis of the peculiarities of interatomic interaction in Cu₂Sb indicates the covalent character of the bonding. The value of the strength of the Cu Cu and Cu Sb bond is evaluated. It is shown that the Cu Cu bond in the Cu₂Sb compound is the most strong one.     

Über die Kristallstrukturdifferenzen der MeSO4 · nH2O-Salztypen

On the basis of the systematized data on the crystal structure of salts of the MeSO₄ · nH₂O type, where Me = Mg²⁺, Ni²⁺, Zn²⁺, Co²⁺, Fe²⁺, Cu²⁺ and n = 0–7, it is established that the differences in the structures of given chemical type metal sulphate crystal hydrates are determined by the nature of the metal ion. The differences in the crystal structure of the heptahydrate, as well as the existence or non-existence of crystal hydrates of some of the ions considered are explained with the electron configuration of the metal ions. The deformation trend of the octahedral coordination of the metal ions considered increases in the following way:      

Controlled synthesis of Cu2O cubic and octahedral nano‐ and microcrystals

Cubic and octahedral Cu₂O nano‐ and microcrystals were selectively synthesized via a simple wet chemical reduction route at room temperature, with CuCl₂ and NaOH as starting reactants, and ascorbic acid or hydrazine hydrate as the reducer. Hydrazine hydrate could be preferentially adsorbed on different crystal faces of Cu₂O, affecting the growth rate along the 〈100〉 to that along the 〈111〉 direction, which resulted in the formation of octahedral Cu₂O crystals. When ascorbic acid was used as the reducer, the growth rate along the 〈100〉 to that along the 〈111〉 direction was different, which resulted in the formation of cubic Cu₂O crystals. The size of cubic and octahedral Cu₂O crystals could be varied by adjusting the molar ratio of OH^– to Cu²⁺. (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)     

Correlations between nuclear magnetic resonance spectra and crystal structure. III. A13C nuclear magnetic resonance study in the solid state of bis(xanthato) complexes of mercury(II); The crystal and molecular structure of bis(n-propyl-dithiocarbonato)mercury(II)

The cross-polarization magic angle carbon-13 nmr spectra of a series of bis(xanthato) complexes of mercury(II) are reported; [Hg(S₂COR)₂] _n R=Me, Et, ⁿ Pr and ⁱ Pr. The spectra correlate well with the known crystal structures of theR=Me, Et, and ⁱ Pr compounds and with that of theR= ⁿ Pr derivative for which a single-crystal X-ray diffraction study is also reported. The X-ray analysis of [Hg(S₂CO ⁿ Pr)₂] _n shows that this compound adopts a two-dimensional structure comprised of connected 16-membered rings which arise as a result of bridgingn-propylxanthate ligands. The mercury atom lies on a crystallographic twofold axis of symmetry and exists in a distorted tetrahedral geometry with two unique Hg-S bond distances of 2.418(3) and 2.835(4) Å. Unit-cell dimensions for [Hg(S₂CO ⁿ Pr)₂] _n are:a=7.371(3),b=8.534(4),c=11.618(4) A andZ=2 for the orthorhombic space groupP2₁2₁2. The structure was refined by a full-matrix least-squares procedure to finalR=0.047 andR _w =0.044 for 899 reflections withI2.5(I). While the solid state nmr spectra provide information on molecular (and crystallographic) symmetry they do not provide sufficient detail to enable structure determination for the [Hg(S₂COR)₂] compounds.     

Crystallization behavior of Ce70−xAl10Cu20Cox (x = 0, 1, 3, 5 at.%) amorphous alloys

The effect of Co addition (substituting for Ce) on crystallization behavior of Ce₇₀Al₁₀Cu₂₀ amorphous alloys has been investigated using X-ray diffraction (XRD), differential thermal analysis (DTA) and transmission electron microscopy (TEM). The Co addition has an obvious effect on topological short-range ordering of Ce–Al–Cu–(Co) amorphous alloys. Moreover, the Co addition can slightly improve the thermal stability of Ce–Al–Cu based amorphous alloys. The 1 and 3 at.% Co additions do not obviously change the crystallization behavior of the Ce–Al–Cu–(Co) amorphous alloys, and the final crystallization products are FCC–CeAlCu(Co)O. However, the 5 at.% Co addition can alter the crystallization behavior of the Ce₇₀Al₁₀Cu₂₀ amorphous alloys. Proper content of Co can effectively suppress the formation of oxide phases during annealing of the Ce–Al–Cu–(Co) amorphous alloys.     

X-ray structure of dodecasodium tricopper(II)bis[nonatungstabismuthate(III) hydrate, a polyoxometalate salt containing α-B-BiW9O33 units

The reaction of [Bi₂W₂₂O₇₄(OH)₂]^12– with Cu²⁺ in hot aqueous solution in the presence of Na⁺ affords the polyoxometalate salt Na₁₂[Cu₃Bi₂W₁₈O₆₆]32H₂O. Single-crystal X-ray analysis [monoclinic, space-group C2/m, a = 33.082(6) Å, b = 19.615(5) Å, c = 14.885(2) Å, = 90.632(12)°, Z = 4; R(F) = 0.065 for 6029 data with I> (I), wR(F ²) = 0.135 for all 8793 independent reflections] shows that the anion [{Cu(H₂O)}₃{BiW₉O₃₃}₂]^12–, on a crystal mirror-plane, has noncrystallographic symmetry close to D_3h. Two B--[Bi^IIIW₉O₃₃]^9– units are linked by an equatorial belt of three Cu(H₂O)²⁺ units. Three Na(H₂O)₂ ⁺ units are also attached in the equatorial plane. The bond geometry is square-pyramidal about each Cu atom and trigonal–prismatic about each Na.     

Two Metal Complexes Supported by {VO<Subscript>3</Subscript>}<Subscript>n</Subscript><Superscript>n−</Superscript> Chains: Hydrothermal Syntheses and Crystal Structures of [M(dpa)V<Subscript>2</Subscript>O<Subscript>6</Subscript>] (M = Zn(II) and Cu(II); dpa = 2,2′-dipyridylamine)

Abstract  

Two new metal complexes supported by {VO₃}_n ⁿ⁻ chains, [M(dpa)V₂O₆] (1, M = Zn²⁺; 2·H₂O, M = Cu²⁺; dpa = 2,2′-dipyridylamine), have been synthesized hydrothermally and characterized by elemental analysis, TG analysis, IR spectroscopy and single-crystal X-ray diffraction. Crystal data: [Zn(dpa)V₂O₆] 1, Triclinic, P-1, a = 9.663(7) ?, b = 10.617(7) ?, c = 15.114(10) ?, α = 105.678(10)°, β = 104.772(9)°, γ = 94.021(10)°, Z = 2; [Cu(dpa)V₂O₆]·H₂O 2·H₂O, Monoclinic, C2, a = 20.543(3) ?, b = 7.2460(9) ?, c = 10.4853(13) ?, β = 111.318(2)°, Z = 4. Complex 1 is constructed from sinusoidal {VO₃}_n ⁿ⁻ chains with {Zn(dpa)}²⁺ fragments spanning the adjacent troughs and crests into an 1D ribbon-like structure. Complex 2 is built up by linking {VO₃}_n ⁿ⁻ chains via pairs of symmetrical {Cu(dpa)}²⁺ fragments into a 2D layered structure. The Zn(II) and Cu(II) ions exhibit tetrahedral and square pyramidal coordination environments, respectively. The formation of the two isomers is attributed to the flexibility of {VO₃}_n ⁿ⁻ chains and the different coordination configurations of the two metal ions. There exist significant π–π stacking and hydrogen bonding interactions in complexes 1 and 2.     

Effect of crystallization behavior on the oxidation resistance of a Zr–Al–Cu metallic glass below the crystallization temperature

The crystallization behavior of Zr_65.0Al_7.5Cu_27.5 (at.%) metallic glass with 753 and 1053 K annealing treatment and its effect on oxidation resistance around the supercooled liquid region at 623 and 663 K was studied. The crystalline phase of bct-Zr₂Cu precipitates for the specimen annealed at 753 K was observed, while duplex structures of bct-Zr₂Cu and Zr₂Al formed in the specimen annealed at 1053 K. The oxidation resistance of the specimen depended on the amount of crystalline precipitates. Regardless of the exposure temperature, the annealed specimens showed higher oxidation resistance than the melt-spun one, especially for the specimen annealed at 1053 K. The formation of numerous crystalline phases of bct-Zr₂Cu and Zr₂Al from the matrix was responsible for improving the oxidation resistance due to their higher oxidation resistance and promotion of the development of Al₂O₃ and oxides of copper. The oxide constituents of the amorphous alloy after long exposure depended on the temperature. The oxide was composed of a large amount of CuO, some tetragonal and monoclinic-ZrO₂ and a minor amount of Cu₂O as well as a slight amount of Al₂O₃ for the melt-spun specimen during exposure at 623 K. Under the 663 K exposure, however, the oxide state of Cu³⁺ in the scale was also detected.     

Synthesis,transformation to octahedron‐like crystals,and gas‐sensing property of six‐horned nanospheres of Cu2O

Single‐crystal six‐horned nanospheres of Cu₂O with a diameter of 760 nm in average were prepared in aqueous solution of CuCl₂and NaOH by using ascorbic acid as the reductant in the presence of sodium dodecyl benzenesulfonate (SDBS) at room temperature. The horn grows along the <100> direction, which is consistent with the protuberant direction of an apex of octahedron. The formation process of six‐horned nanospheres included two steps: the formation of Cu₂O nanospheres via Ostwald ripening process, and the appearance of horns on the surface of nanospheres under low concentration of SDBS. As increasing the concentration of SDBS, the six‐horned nanospheres could be transformed into octahedron‐like Cu₂O. And at the same concentration of SDBS, keeping the volume ratio of water and ethanol in mixed solutions as 1:1, Cu₂O octahedra were obtained. Moreover, gas‐sensing property showed that six‐horned nanospheres of Cu₂O had higher sensitivity compared with Cu₂O nanospheres and Cu₂O octahedra to ethanol gas (© 2011 WILEY‐VCH Verlag GmbH & Co.

Phase stability and oxygen doping in the Cu-N-O system

A growth stability diagram for the CuNO system has been determined in the temperature range 250-500 °C for a thermally activated CVD process, based on copper (II) hexafluoroacetylacetonate (Cu(hfac)₂), NH₃ and H₂O. Without any addition of water only Cu₃N was obtained. Addition of water introduces oxygen into the Cu₃N structure to a maximum amount of 9 at% at a water/nitrogen molar ratio of 0.36 at 325 °C. Above this molar ratio Cu₂O starts to deposit, in addition to an oxygen doped Cu₃N phase. Only Cu₂O is deposited at large excess of water.     

Crystal Data,Electrical Resisitivity and Mobility in Cu3In5Se9 and Cu3In5Te9 Single Crystals

X-ray powder diffraction data were obtained for Cu₃In₅Se₉ and Cu₃Te₉, which were found to crystallize in orthorhombic and tetragonal systems, respectively. The electrical resistivities and Hall mobilities of these compounds were investigated in the temperature range 35–475 K. Cu₃In₅Se₉, was identified to be n-type with a room temperature resistivity of 3 × 10³ Ω·cm which decreases with increasing temperature. For T < 65 K impurity activation energy of 0.03 eV and for T > 350 K onset of intrinsic conduction yielding a band gap energy of 0.99eV were detected. The neutral impurity scattering was found to dominate at low temperatures, while in the high temperature region thermally activated mobility was observed. Cu₃In₅Te₉ exhibits p-type conduction with a room temperature resistivity of 8.5 × 10⁻³ Ω·cm decreasing sharply above 400 K and yielding an impurity ionization energy of 0.13 eV. The temperature dependence of mobility indicates the presence of lattice and ionized impuritiy scattering mechanisms above and below 160 K, respectively.     

Synthesis and Crystal Structure of Copper(II)-Hexafluoro-Acetylacetonate Complexes with Pyridyl-Substituted Nitronyl and Imino-Nitroxide Radicals

Abstract  

A one-dimensional chain compound was formed by copper (II) hexafluoroacetylacetonate (hfac) and nitroxide radical 2-(4-pyridyl)-4,4,5,5-tetramethyl-imidazoline-1-oxyl-oxide (NITpPy). The product was structurally characterized by single crystal X-ray diffraction. [Cu₂(hfac)₄NITpPy] _n crystallizes in the monoclinic C₂/c space group with a = 19.70(2), b = 16.834(19), c = 15.274(18) ?, β = 119.073, V = 4427(9) ?³, Z = 4, R = 0.0699 wR ₂ (all data) = 0.1752. In the compound, two different Cu(hfac)₂ units are bridged by NITpPy. The nitrogen atom of pyridine ring is coordinated with Cu(II) ion to afford a three-spin complex. Cu(II) ions of Cu(hfac)₂ and the oxygen atoms of nitronyl nitroxide formed weak coordination bonds with the bond length 2.495(8) ?.     

Synthesis and crystal structures of two copper(I) π-complexes with 1-allyloxybenzotriazole of CuBr?C6H4N3(OC3H5) and 2CuCl?C6H4N3(OC3H5) compositions

Both compounds of CuBr⋅C₆H₄N₃(OC₃H₅) (sp. gr. P1, a = 7.633(1) Å, b = 9.987(1) Å, c = 14.898(2) Å, α = 104.75(1)^∘, β = 94.76(1)^∘, γ = 106.90(1)^∘) (I) and 2CuCl⋅C₆H₄N₃(OC₃H₅) (sp. gr. Cc, a = 11.2483(4) Å, b = 16.7076(6) Å, c = 7.2948(3) Å, β = 118.612(2)^∘) (II) composition were prepared by alternating-current electrochemical synthesis. In I due to a bridging function of organic moieties 16-membered cycles appear which are combined into ribbons {Cu₂Br₂[(C₆H₄N₃(OC₃H₅)]₂}_n. Each of two crystallographically independent copper atom possesses a trigonal-pyramidal arrangement with different degree of tetrahedral distortion. Distinctive numbers of hydrogen bonds around Br1 and Br2 atoms cause rather appreciable distinctions in copper–olefinic bond interaction effectiveness for each metal atom. In II Cu₂Cl₂ rhombs are joined to infinite chains oriented along [010] direction. Each ligand molecule is also coordinated through the C=C—bond of the allylic group to copper atom of one inorganic chain and through the nitrogen atom to a metal atom belonging to another copper-halide chain. Cu1 atoms is tetrahedrally surrounded by three chlorine atoms and nitrogen one, whereas a trigonal-planar arrangement of Cu2 atom is formed by two halogen atoms and slightly disordered olefinic group.
