Abstract:

ZusammenfassungVorgestellt wird der Fall eines 76-jährigen Rheumatikers mit einer seit 21 Jahren dosisvariablen Dauertherapie mit Sulfasalazin, Chloroquin, Prednisolon und Methotrexat und endoprothetischem Ersatz beider Hüftgelenke und des linken Kniegelenkes sowie Wechselprothetik der linken Hüfte. Nach einem diaphysären Ermüdungsbruch mit erforderlichem totalem Femur zeigen die histologischen Befunde des Explantates in drei repräsentativen Schnittebenen die ungestörte Osteointegration eines Prothesenschaftes mit Oktaeder-Querschnitt und Mehrpunktabstützung in einem extrem geschwächten Knochenlager. Der hier gewählte Oktaederschafttyp mit Mehrpunktfixation und nicht intendierter endofemoraler Aussteifung durch erzwungenen vollflächigen Primärkontakt führt zur ungestörten Osteointegration.

Abstract:

Comparative investigations are carried out for spectral (Raman) electrical and structural properties of V2O5 single crystals and polycrystalline samples obtained by IR laser light illumination of pure metallic samples in an oxidizing atmosphere (air). It is shown that the structures grown on metallic plates in the field of laser light are predominantly V2O5 polycrystals. Raman measurements reveal that the main peaks, which are characteristic for single crystals, are also present in laser-driven samples but with different intensities. Some peaks are attributed to laser-grown thick films, which are not present in the single-crystalline phase. There are shifts in the peak positions indicating the existence of different force constants for films as compared with crystals. The activation energies obtained from the electrical properties (conductivity, impedance versus temperature) yield similar values except for the anisotropic characteristics of the single crystal where the values are a bit different along different crystallographic axes (unlike the polycrystalline oxide films made by the laser). The single-crystalline phase has a well-defined layered structure with well-defined shapes showing formed units of truncated oktaeders, while the film structure shows randomly distributed tubular micron-size structures with empty holes at the peripheral part of the irradiated area, and nanoscaled long and thin tubes well oriented along the direction of the incoming laser light in the central part of the irradiation spot.

It crystallizes in the space group Pmma (No. 51) with the lattice constants a = 2249.4(4), b = 383.7(1), c = 1079.1(1) pm. Within the crystal structure the C atoms and the O atoms are surrounded by Y atoms octahedrally and tetrahedrally, respectively. The Y6C octahedra and Y4O tetrahedra are condensed to form ondulated layers, which are separated by double layers of I atoms.

Abstract:

AbstractThe title compound was prepared by high-pressure reaction of rhenium metal with technical grade (i.e., Na containing) KO2 in a modified Belt-type apparatus (20 kbar, 1000 °C, 60 min, Au capsule). The amber-coloured crystals are very hygroscopic and decompose rapidly when exposed to air. K3NaRe2O9 crystallizes hexagonally, space group P63/mmc, with a = 6.012(1), c = 14.342(14) Å, c/a = 2.386 and Z = 2. The structure was refined to R = 0.031, Rw = 0.023 for 422 independent, absorption-corrected reflections with l > σ (I). K3NaRe2O9 is isostructural with 6H-BaTiO3, a perowskite variant, and contains Na and Re in octaedral coordination. Two ReO6 octahedra are face-sharing, thus creating a Re2O9 double octahedron with a Re-R e distance of 2.92 Å.

Abstract:

The new compounds Y7I12C2N and Ho7I12C2N have been prepared by reaction of stoichiometric amounts of the metals (RE), REI3, REN and C in closed Ta capsules at 1150 and 1120K, respectively. Pure samples of the compounds were obtained after 5 days annealing time. The crystals with xenomorphic shape are olive-green (Y7I12C2N) or red-brown (Ho7I12C2N) in colour and sensitive to air and moisture. Y7I12C2N crystallizes in the space group P 1̄ (No. 2) with lattice constants a = 971.24(7), b = 1030.38(7), c = 1673.58(11) pm and α = 101.366(5), β = 92.758(5), γ = 112.799(5)°. According to Guinier photographs Ho7I12C2N is isotypic with the lattice consiants u - 968.8(3), b = 1028.7(3), r. = 1667.8(5) pm and α = 101.31(2), β = 92.78(2), γ = 112.80(1)°. In the structure the C atoms are present as C2 units with a C -C distance of 144 pm. These C2 units are octahedrally coordinated by Y atoms (o1). The N atoms are in the center of Y4 tetrahedra, which are linked via a common edge to form double tetrahedra (t2). By condensation of N-centered double tetrahedra (t2) with a C2-centered Y octahedron (o1) the characteristic units o1t2o1 are formed. The I atoms coordinate all free edges and corners of these units and connect them via Ii - Ia contacts parallel [100] and [001]. The compounds are semiconducting. Ho7I12C2N exhibits Curie-Weiss behaviour with θ = 15(1) K and μeff = 10.5(1) μB.

Abstract:

Abstract Single crystals of the new compound CaNi(VO)(PO4)2 have been prepared by solid state reactions below the melting point of the oxide mixture in evacuated quartz tubes. X-ray investigations led to orthorhombic symmetry, space group D2h16-Pnma, a =14.113(1), b =6.408(1), c = 7.364(1) Å, Z = 4. The crystal structure shows 1∞[NiO4] and 1∞[VO6P2O3] polyhedra chains closely related to analogous chains in the isotypic compound CdV2O(PO4)2. The short V -O distance of 1.66 Å indicates a vanadyl group as the main difference to CdV2O(PO4)2. The short O-O distance of 2,395 Å of the edge-sharing PO4 tetrahedra and VO6 octahedra is discussed.

Abstract:

Abstract Using 293 K diffractometer intensity data, the structures of [H3N(CH2)3NH3]TeCl6 and [H3N(CH2)3NH3]SnCl6 have been determined by single crystal X-ray technique and refined to a final of 0.027 and 0,029, respectively. The yellow crystals of the tellurate are orthorhombic (space group Pnma) with a = 22.952(2), b = 7.5414(4), c - 7.801(1) Å and Z = 4. This structure contains distorted TeCl62- octahedra (distances Te - Cl min. 2.426(1), max. 2.672(1) Å ) with approximate 2mm point symmetry. In contrast, the SnCl62- ion in the second title com pound is octahedral with only small deviations from m 3m symmetry (distances Sn -Cl mean: 2.438(3) Ä ). The colourless crystals of this tin com pound are orthorhombic (space group Pnma) with a - 17.6082(9), b = 7.1809(3), c = 10.190(1) Å and Z = 4. Considering the TeX62- (X = Cl, Br, I) salts known to date, a distorted species is an exception, although a distortion is predicted by the VSEPR theory. The results agree with the rules for the appearance of a static stereochemical effect of the lone pair electrons in the TeX62- species
