 Title    Zur Koordinationschemie des 2,2'-Dipyridyldiselenids (PySeSePy), Teil 2 [1]  
 Abstract    The coordination chemistry of 2,2'-dipyridyldiselenide (PySeSePy) towards mangane­ se, copper and zinc centres has been studied. The complexes [MnBr2-/V,/V'-(PySeSePy)] (1), [CuBr2-/V,/V'-(PySeSePy)] (2), [Cu-(//-Br)-7V(/V'-(PySeSePy)]2 (3), [Cu-()U-Br)-{p-N,N'-(PySeSePy)}]" (4), [Cu-(/i-Cl)-/V,W'-(PySeSePy)]2 (5), [Zn(OOCC6F5)2-/V,/V'-(PySeSePy)] (6) and [Z n (0 S 0 2CF3)2-./V>/V'-(PySeSePy)] (7) have been synthesised and the crystal structures of 1, 3, 4 and 6 determined. 1, 3 and 6 display seven-membered metallacycles with tetrahedral coordination of the metal centres. In these cases 2,2'-dipyridyldiselenide acts as a chelating ligand. In the polymeric complex 4, 2,2'-dipyridyldiselenide acts as a bridging ligand. All com­ plexes display selenium-selenium single bonds with an average length of 232 pm. In contrast to the analogous chloro and nitrato complexes, the zinc complexes 6 and 7 are not dissociated in solution, as evidenced by 77Se NMR experiments. The corresponding resonances are shifted downfield in comparison with the ligand.

 Title    CsCu3Dy2S5 und CsCu3Er2S5 : Zwei isotype quaternäre Sulfide der Lanthanoide mit Kanalstrukturen CsCu3Dy2S5 and CsCu3Er2S5: Two Isotypic Quaternary Sulfides of the Lanthanides with Channel Structures  
 Abstract    Orthorhombic single crystals of CsCu3 Dy2 S5 (a = 397.54(4), b = 1414.8(1), c = 1685.7(2) pm) and CsCu3 Er2 S5 (a = 394.82(4), b= 1410.9(1), c = 1667.2(2) pm; both Cmcm, Z = 4) are obtained as by-products (pale yellow or pink transparent needles) in attempts to synthesize CuMS2 (M = Dy and Er) through the oxidation of elemental copper, dysprosium and erbium, respectively, with sulfur (molar ratios: 1 :1 :2) in the presence of equimolar amounts of cesium chloride (CsCl) as fluxing agent at 900 °C within fourteen days from torch-sealed evacuated silica tubes. Their crystal structure contains octahedral [MS6]9~ units (d(M-S) = 269 -282 pm) which share edges and vertices to form layers ^ {(M 2 S5)4_} parallel (010). These are three-dimensional-ly interconnected along [010] by two crystallographically different Cu+ cations in tetrahedral coordination of S2_ anions (d(Cu-S) = 227 -269 pm) according to ^{(Cu^MtSs)-}. Thereby a likewise layered substructure 2,{(Cu3 S5)7 -} is formed parallel (010) by edge-and vertex-linking of all [CuS4]7~ tetrahedra. Large channels within the <£>{(Cu3 M2 S5)~ } network spread along [100] and suit well to take up the highly coordinated Cs+ cations, which are surrounded by eight plus one S2~ anions at distances between 340 and 358 pm (8 x) with the ninth ligand 420 -421 pm apart in the shape of (2+7)-fold capped trigonal prisms.

 Title    Copper Contamination Mechanism of Silicon Substrates from HF Solutions  
 Abstract    The contamination of silicon wafers from dilute HF solutions containing ultratrace levels of metallic ion impurities is a subject of constant interest. The mechanism of copper electroless deposition from HF onto monocrystalline silicon was investigated using a new electrochemical cell, which proved to be a very sensitive detector for in situ characterization of silicon surfaces. Upon addition of copper trace amounts, the open-circuit potential was observed to shift rapidly towards more positive values at a rate nearly proportional to the copper concentration. All poten-tial/time curves tend to reach a limiting value of the potential, while quantitative measurements of radioactive tracers revealed that during a few tens of minutes, copper ions were continuously reduced on the silicon surface. Electrochemical potentials and voltammetric measurements were interpreted in terms of the mixed potential theory and led to the conclusion that copper nuclei act as a catalyst which enhances the cathodic activity for protons reduction. The model was supported by AFM observations which demonstrated the initiation of corrosion pits around the nuclei.

 Title    XPS Spectra of Copper and Nickel Biuret Complexes — Observations of Intense Satellite Structure in the 2P Spectrum of a Copper(III) System  
 Abstract    A series of copper and nickel biuret complexes has been studied by X-ray photoelectron spectroscopy (XPS). The results include one of the first reports of the XPS spectrum of a copper(III) complex. Significantly, this diamagnetic complex exhibits intense satellite structure in both the Cu 2P3/2 and Cu 2Pi/2 regions. The isoelectronic nickel(II) complex shows no comparable satellite structure.

 Title    Copper(II) Complexes Containing 3-n-Nonylcatechol: Preparation and Ligand Oxidation  
 Abstract    Ternary copper(II) complexes containing the dianion of 3-n-nonylcatechol and a number of bidentate nitrogen containing counter ligands have been prepared and charac-terized. It has been demonstrated that, in the presence of oxygen, the catecholato ligand undergoes intradiol ring cleavage in a fashion similar to that carried out by intradiol aromatic dioxygenases. The 3-n-nonylcatecholato ligand was chosen as an analog for the naturally occuring 3-pentadecylcatechols or "urushiols" which are the active allergens in plants such as poison ivy.

 Title    The Crystal Structures of U2Cu3 AL and UCUA12, and their Relationship with Some Other Phases in the System U-Cu-Al  
 Abstract    X-ray investigations of a great number of samples along the specifically chosen tie-lines in the isothermal sections of the system U-Cu-Al (800 °C) indicated the existence of two new ordered ternary phases, i.e. U2CU3A1 and UCUA12. The first one is hexagonal (S. G. P63/mmc, MgZn2-type), with a = 5.065 ± 0.005 A, c = 8.307 ± 0.005 A and c/a = 1.640. The ordered atomic arrangement of all atoms, as confirmed by trial and error method is consistent with a rather uncommon superstructure of the MgZn2-type. UCUA12 is tetragonal, a = 3.857 ± 0.005 A, c = 8.736 ± 0.005 A, c/a = 2.265, probable space group is I4/mmm, and represents an ordered ternary structure variant of the TiAl3 type. The crystal structures of these two new phases were correlated, in terms of stacking sequences, with those which were identified in this system previously.

 Title    Copper Complexes with the Ligand [Cp2MoH2]  
 Abstract    The reaction of CuCl with [CP2M0H2] yields the complex [Cu(Cp2M oH2)2Cl]. An X-ray structure analysis shows that the coordination of the copper(I) ion by two [CP2M0H2] lig­ ands and the chloride ion is pseudo-trigonal planar. The hydride ligands were located by using difference Fourier methods. A manifold of reactions took place when an aqueous so­ lution of CUSO4 was treated with a solution of [Cp2M oH 2] in dichloromethane in a 1:2 molar ratio. The X-ray structure analysis established a polymeric structure of the complex [Cu(Cp2MoH2)2Cu(Cp2M oH2)S0 4 ]" with two different copper centers.

 Title    Synthesis and Structural Study of the Thermochromic Compounds Bis(2-amino-4-oxo-6-methylpyrimidinium) Tetrachlorocuprate(II) and Bis(2-amino-4-chloro-6-methylpyrimidinium) Hexachlorodicuprate(II)  
 Abstract    The compound bis(2-am ino-4-oxo-6-methylpyrimidinium) tetrachlorocuprate(II) 1 contains CuCU2-square-planar anions, and bis(2-am ino-4-chloro-6-m ethylpyrim idinium) hexachlorod-icuprate(II) 2 quasi-planar CU2CI62-anions. Both compounds show thermochromic behaviour. This phenomenon has been studied by X-ray crystallography at variable temperature, with the result that no major change is observed in the geometry o f the copper atom. Thus it is possible to assume som e influence o f the hydrogen bonds and o f the different geometries o f interme­ diate states on the color o f the compounds due to the modifications provoked in the L —>M charge transfer and in the energy o f the metal d-d transitions. Magnetic measurements o f the compounds give information on magneto-structural correlations. Compound 1 is ferromagnetic (Tc = 20 K) due to the perpendicular arrangement o f the square anions that allows exchange pathways only via Cu-Cl -Cu , H-bonding or cationic n electron interactions. Compound 2 shows a very complicated behavior at low temperature with local antiferromagnetic fluctua­ tions.

 Title    X-ray Investigations of Liquid Bismuth-Copper Alloys  
 Abstract    Liquid copper, bismuth, and eleven bismuth-copper alloys were investigated at temperatures above the liquidus with X-ray diffraction. The experimental procedure was adjusted to reduce the effects of evaporation. The Faber-Ziman total structure factors S(Q) feature a splitting of the first maximum and negative values for Q around 1 A -1 in a large concentration range. The results are compared to previous neutron diffraction results by Zaiss and Steeb, to square-well potential model calculations by Gopala Rao and Satpathy and to a simple segregation model. The segregation model reproduces the features qualitatively. Partial structure factors are assessed by fitting both neutron and X-ray scattering results with reverse Monte-Carlo simulation.

 Title    in Mischkristallen BaXu^Zn^yFg Cu 2+ in Tetragonally Compressed Octahedral Coordination - Spectroscopic Investigations of Mixed Crystals Ba2Cii^.Zn1_xF6  
 Abstract    Usually the Jahn-Teller effect of Cu 2+ in a regular octahedral host lattice site leads to a tetragonal elongation with a small o-rhombic component. If the relevant crystallographic site is slightly tetragonally compressed however in the host lattice structure already — as in Ba 2 ZnF6 -the Jahn-Teller effect may stabilize this distortion symmetry as well. This can be deduced from the EPR-spectroscopic g M -values of 1.99 for the mixed crystals Ba^Zni.^Cu^Fg up to x = 0.3. The angular overlap parameters obtained from the ligand field spectra suggest in addition, that the tetragonal compression of the CuFß polyliedra is considerable, with CuF distances of about 1.90 A (2x) and 2.14 A (4x), respectively. Increasing cooperative elastic interactions between the CuFß polyhedia in the (001) planes at larger Cu 2+ -concentrations induce tetragonally elongated octahedra (with a small o-rhombic component) in antiferrodistortive order at x > 0.6. This cooperative Jahn-Teller order, which is characteristic for Ba2CuF6, can be verified simply by acentric displacements of the F~-ligands connecting two Cu 2+ -ions in the (001) planes.
