 Title    The Stannides RE R hSn (RE = Ho -Yb) and ScTSn (T = Pd, Pt) -Structure Refinements and 119Sn Mössbauer Spectroscopy  
 Abstract    The stannides RERhSn (RE = Ho -Yb) and ScTSn (T = Pd, Pt) were prepared by reaction of the elements in sealed tantalum tubes in a high-frequency furnace, by arc-melting, or by a tin-flux technique in quartz tubes. The rhodium based stannides crystallize with the ZrNiAl type structure, space group P62m. The four structures were refined from single crystal X-ray data: a = 754.5(3), c = 377.1(1) pm, wR2 = 0.0357, 233 F 2 values for HoRhSn, a = 753.3(1), c = 372.16(8) pm, wR2 = 0.0721, 233 F 2 values for ErRhSn, a = 753.7(3), c = 369.0(2) pm, wR2 = 0.0671,233 F 2 values for TmRhSn, and a = 753.17(5), c = 366.53(4) pm, wR2 = 0.0566, 180 F 2 values for YbRhSn with 14 parameters for each refinement. ScPdSn and ScPtSn adopt the HfRhSn type, a superstructure of ZrNiAl, space group P62c: a = 747.5(1), c = 710.2(1) pm, for ScPdSn, and a = 738.37(9), c = 729.47(9) pm, wR2 = 0.0452,369 F 2 values, 18 variables for ScPtSn. Structural motifs in these stannides are transition metal centered trigonal prisms formed by the rare earth and tin atoms. While these prisms are regular in the rhodium based stannides, significant distortions occur in ScPdSn and ScPtSn. The formation of the superstructure can be ascribed to packing reasons. The shortest interatomic distances occur between the transition metal (T) and tin atoms. These atoms form three-dimensional [FSn] networks in which the rare earth atoms fill distorted hexagonal channels. The series RERhSn displays a somewhat unique behavior. The a lattice parameter is more or less independent of the rare earth element, while the c lattice parameter shows the expected lanthanoid contraction. ll9Sn Mössbauer spectroscopic data of the rhodium stannides show signals at isomer shifts varying from 1.77 to 1.82 mm/s subject to quadrupole splitting between 0.75 to 0.82 mm/s.

 Title    Synthesis, Structure, and Magnetic Properties of EuAgCd and YbAgCd  
 Abstract    New intermetallic compounds EuAgCd and YbAgCd were synthesized in quantitative yield by reaction of the elements in sealed tantalum tubes in a high-frequency furnace. Both com­ pounds were investigated by X-ray diffraction on powders and single crystals: KHg2 type, Imma, a = 490.41(8), b = 771.0(1), c = 834.4(2) pm, wR2 = 0.0624, 255 F values, 12 variables for EuAgCd, and MgZn2 type, Pb^/mmc, a = 584.66(5), c = 946.83(9) pm, wR2 = 0.0502, 187 F 2 values, 11 variables for YbAgCd. Owing to the very small difference in scattering power, no long range ordering of the silver and cadmium atoms is evident from the X-ray data, although Ag-Cd ordering is expected. The silver and cadmium atoms randomly occupy the mercury and zinc positions of the KHg2 and MgZn2 type structures, respectively. In EuAgCd the [AgCd] substructure consists of strongly puckered, orthorhombically distorted Ag3 Cd3 hexagons, while a three-dimensional network of face-and comer-sharing tetrahedra is observed in YbAgCd. The rare earth atoms fill the space between the Ag3 Cd3 hexagons (EuAgCd) or within the three-dimensional tetrahedral network (YbAgCd). Magnetic susceptibility measurements in­ dicate Pauli paramagnetism for YbAgCd and Curie-Weiss behavior above 60 K for EuAgCd with an experimental magnetic moment of 7.82(3) /j b/Eu indicating divalent ytterbium and europium. Ferromagnetic ordering at Tc = 28.0(5) K is observed for EuAgCd. At 2 K and 5 T the saturation magnetization is 5.85(5) /iß/Eu.

 Title    Die Kristallstruktur von Thiocyanato(2-dimethylaminoäthanolato)kupfer(II) The Crystal Structure of Thiocyanato(2-dimethylaminoethanalato)copper(II)  
 Abstract    The crystal structure of the title compound has been determined from three-dimensional X-ray diffractometer data. Crystals are monoclinic, space group P2i/c with 8 CU(C4HIONO)SCN units in a cell of dimensions a = 11.951(4), b = 8.954(3), c = 16.805(6) Ä, and ß = 107.5(1)°. The structure was refined by least squares techniques to a final discrepancy factor of 0.041 based on 2234 observed independent reflexions. The compound is polymeric with copper atoms alternately bridged by two oxygen atoms and two thiocyanato groups. The coordination geometry around each copper atom is distorted square pyramidal. The basal plane consists of the two bridging oxygen atoms (mean value Cu-O: 1.914(3) A), the amino nitrogen atom (mean value Cu—N: 2.035(3) A) and the nitrogen atom from the thiocyanato group (mean value Cu-N: 1.908(3) A) while the axial coordination site is occupied by a sulfur atom from a thiocyanato group (mean value Cu-S: 2.979(2) A) centrosymmetric to the first. The magnetic susceptibility of the compound shows a broad maximum at 200 K.

 Title     
 Abstract    Upon use of a synthetic method reported earlier by us respective alloys of Na/Sn, Na/Ge and Na/Sb are dissolved in ethylene-diamine and the title compounds precipitated from the solutions in high yield. By recrystal-lisation well shaped, stable crystals are obtain-ed. The crystal structure of [Na4 • 7 en]Sn9 confirms the presence of a Sn9 4 ~-polyhedron which had been suggested by us on the basis of other investigations. The Sn9 4_ -polyhedron may be described as a distorted tricapped trigonal prism. Ethylenediamine is coordi-nated to Na+-ions exclusively.

 Title    Fluorreiche Oxofluorovanadate(V): Die Kristallstruktur von [enH2] [VOF5]  
 Abstract    The crystal structure of triclinic [enH2][VOF5], prepared in aqueous solution, has been determined from X-ray diffractometer data (i? = 0.076 for 527 reflections). The structure contains monomeric [VOFs] 2--ions. The bond distances are 1.54(1) Ä (terminal oxygen), 1.80(1) (average for the cis-fluorine atoms) and 2.10(1) Ä for the fluorine atom in trans-position to the terminal oxygen atom. This fluorine atom is involved in strong hydrogen bonds originating from the [NHaCH^CH^NEy 2 " 1 -cation with cisoid conformation. Earlier results about the existence of K2VOF5 could not be confirmed.

 Title    Röntgenographische Strukturuntersuchung von Cäsiumhexaoxo-tetrahydroxo-pentaborat-2-dimethylsulfoxid X-ray Study of the Structure of Cesiumhexaoxo-tetrahydroxo-pentaborate-2-dimethyl Sulfoxide  
 Abstract    The compound Cs[Bs0 6 (OH)4 ] • 2 DMSO was prepared by hydrolysis of tris(methoxy)-borane in organic solvents with small amounts of water in presence of cesium ierf-butylate and recrystallized in DMSO (dimethyl sulfoxide). Cs[Bs0 6 (0 H)4 ] • 2 DMSO crystallizes in the monoclinic space group P2i/a with a = 9.593(2), 6 = 19.179(4), c = 11.585(2) Ä, ß = 119.99(2)° and Z — 4. The crystal structure was determined by single-crystal diffracto­ meter data and refined to a conventional R value of 9.9%. The crystal structure consists of chains of pentaborate anions [Bs0 6 (OH)4 ]-linked by hydrogen bonds. The cesium cation and the DMSO molecules join the chains to sheets by coordination and hydrogen bonds respectively.

It can be shown that small amounts of CaO stabilize the monoclinic B-Typ of rare earth oxides. Phase (A) and (B) cannot be seen as a stabilized B-type crystal because they have an new crystal structure with space group C.7h-P 2 i/m, a = 656.6, b = 356.7, c = 529.4pm , ß = 92.3°; a = 650.2, b = 352.4, c = 584.5, ß = 92.3°.

 Title    Cyclische Diazastannylene, DI 1 Die Kristall-und Molekülstruktur der monoklinen Phase von 1.3-Di-feri-butyl-2.2-dimethyl-1.3.2.4A 2 -diazasilastannetidin The Crystal and Molecular Structure of the Monoclinic Phase of l,3-Di-feri-butyl-2,2-dimethyl-l,3,2,4A 2 -diazasilastannetidine  
 Abstract    The crystal and molecular structure of the monoclinic phase of l,3-di-£eri-butyl-2,2-dimethyl-l,3,2,4A 2 -diazasilastannetidine has been determined from three-dimensional X-ray data collected on a two-circle diffractometer at —120 °C (MoKa radiation, 2623 re-flexions, R — 0,050). The crystals are monoclinic, space group C 2/c, with cell dimensions a = 10.655(5), b = 25.75(1), c = 17.33(1) A, ß = 106.8(1)° and Z = 12. Four monomeric (crystal site symmetry 2 (C2)) and four dimeric units (crystal site symmetry I (Cj)) are present in the structure interacting over tin-tin (3.68 A). Remarkable are the very short Sn-N bond (2.09 A) in the monomer and the donation bond Sn-N (2.39 Ä) in the dimer. The coordination of the tin atoms in the different units is discussed in detail.
