    Description / Table of Contents: Structure Redetermination and Magnetic Studies on Mn2SnS4The crystal structure of Mn2SnS4 was redetermined by single crystal and powder X-ray studies. It has a deficient NaCl superstructure crystallizing in the orthorhombic space group Cmmm proposed by Wintenberger and Jumas in 1980 (Z = 2, a = 740.7(1), b = 1047.5(1) and c = 366.7(2) pm, Rf = 1.4% for 266 unique reflections with I 〉 0σ1). Some additional reflections, which are not compatible with this cell, can be refined assuming formation of twinned trilling crystals. Mn2SnS4 undergoes antiferromagnetic ordering below 160 K. The effective magnetic moment μeff of Mn2+ is 5.92 B.M. The IR and Raman spectra display 5 and 3 bands in the range 150-320 cm-1, respectively.
    Notes: Die Kristallstruktur von Mn2SnS4 wurde mittels Röntgeneinkristall- und Röntgenpulver-Messungen nachbestimmt. Mn2SnS4 besitzt eine defiziente NaCl-Überstruktur und kristallisiert, wie von Wintenberger und Jumas [6] vorgeschlagen, in der orthorhombischen Raumgruppe Cmmm (Rf = 1,4% für 266 unabhängige Reflexe mit I 〉 0σ1). Die in dieser Zelle nicht indizierbaren Reflexe können unter der Annahme einer Mehrlingsbildung verfeinert werden. Das effektive magnetische Moment μeff von Mn2+ beträgt 5,92 B.M. Unterhalb 160 K liegt eine antiferromagnetische Ordnung vor. Die IR-und Raman-Spektren zeigen 5 bzw. 3 Banden im Bereich von 150-320 cm-1.

    Description / Table of Contents: Crystal Structure Determination of a Strontium Hydride Imide Nitride - Sr2(H)N/SrNH resp. Sr2(D)N/SrND - by X-Ray, Neutron, and Synchrotron RadiationStrontium reacts with nitrogen and hydrogen resp. deuterium under well defined conditions to a phase containing hydride, imide and nitride ions.Sr is evaporated at 1000°C. The Sr vapor reacts with N2 and H2 resp. D2 (p(N2) = p(H2/D2) = 50 mbar) in the gas phase. The product crystallizes as orange-yellow resp. black needles at 800°C.Neither X-ray single crystal nor X-ray and neutron powder diffraction data led to an acceptable model for the crystal structure. A high resolution diffraction experiment with synchrotron radiation gave the needed informations:Splitting of reflections led to a model in R3m with a = 3.870(1) Å and c = 18.958(3) Å. Further split reflections indicate, that the crystals contain areas where SrNH is a second phase besides Sr2(H)N. Neutron diffraction data (measured at 2 K, 10 K, 300 K and 505 K) were interpreted by a two phase model with Sr2(D)N/SrND: In a slightly distorted cubic close packing of Sr-atoms hydride and nitride resp imide ions occupy each by one third octahedral sites fully and in an ordered way.
    Notes: Strontium reagiert mit Stickstoff und Wasserstoff bzw. Deuterium unter definierten Bedingungen zu einer Phase, in der Hydrid-, Imid- und Nitridionen nebeneinander vorliegen.Sr wird bei bei 1000°C verdampft. Die Reaktion mit N2 und H2 bzw. D2 (p(N2) = p(H2/D2) = 50 mbar) findet in der Gasphase statt. Das Produkt kristallisiert als orange-gelbe bzw. schwarze Kristallnadeln bei 800°C.Weder aus Röntgen-Einkristall- noch aus Röntgen- oder Neutronenbeugungs-Pulverdaten konnte die Kristallstrukur eindeutig bestimmt werden. Erst ein hochauflösendes Beugungsexperiment mit Synchrotronstrahlung am Pulver gab entscheidende Hinweise auf ein Strukturmodell:Aufspaltungen von Reflexen können nur mit einem Modell in R3m mit a = 3,870(1) Å und c = 18,958(3) Å erklärt werden. Zusätzliche Reflexe zeigen, daß in den Kristallen neben Sr2(H)N Bereiche mit SrNH als zweiter Phase vorhanden sind. Die Verfeinerung von Neutronenbeugungsdaten (Messungen bei 2 K, 10 K, 300 K und 505 K) mit einem Zweiphasenmodell Sr2(D)N/SrND führt zu einem sinnvollen Ergebnis: In einer leicht verzerrten kubisch dichten Anordnung von Sr-Atomen besetzen schichtenweise in Domänen Hydrid- und Nitridionen bzw. Imidionen Oktaederlücken vollständig und geordnet jeweils zu einem Drittel.

    Notes: Organotungsten-selenolato complexes were prepared in moderate yields by insertion of selenium into the alkali metaltungsten bonds of MSeW(CO)3cp (M = Li, Na) and subsequent reactions with the organohalides o-, m-, and p- C6H4(CH2Br)2, C6H5CHBr2, m-C6H4(CHBr2)2 and C6H5CCl3. The 77Se-NMR data of the new complexes are discussed and compared with those of related complexes derived from organomonohalides. Moreover, the X-ray crystal structures of C6H5CH2W(CO)3cp (1), μ-[m-C6H4{CH2SeW(CO)3cp}2] (3), μ-[p-C6H4{CH2SeW(CO)3cp}2] (4), and C6H5CH[SeW-(CO)3cp]2 (5) were determined. In complex (1), the W-CH2 bond length is 2.374 Å; the W-Se bond lengths in the complexes 3, 4 and 5 are all in the range 2.625-2.655 Å, corresponding to W-Se single bonds.
