 Title    Eine neue Darstellungsmethode für Caesiumhydroxid A New Preparative Method for Cesiumhydroxide  
 Abstract    Cesiumhydroxide has been prepared by the reaction of CsOH • H2O with CSNH2 in super-critical ammonia. Thermochemical data for CsOH are given in the range from 100 to 640 K. The x-ray investigation of the compound above 497.5 K shows a sodium chloride type of struc-ture with a = 6,427 (5) A at 503 K. The lattice constants for the rhombic modification at 298 K are a = 4,350 (3) A, b = 11,99 (1) A and c = 4,516 (3) A. The cell contains four formula units. The structure is of an anii-NaOH type.

 Title    Hydroxy Complexes of Gold 2. Calcium Aurates [1]  
 Abstract    Two calcium aurate phases have been obtained as single crystals, phase 1 from H AUC1 4 + Ca(OH) 2 and phase 2 from NaAu(OH) 4 + Ca(C10 4) 2 . An X-ray structure determination of 1 shows its composition to be Ca 2 (0H) 3 (H 2 0) 4 [Au(0H) 4 ]. The apparent space group is Cmcm, but this corresponds to a sub-cell of the true structure. The disordered Cmcm structure was refined to R 0.032 for 813 reflections. The coordination geometry is square planar at gold (Au-O 1.97, 1.99 Ä), cubic at Ca(l) and octahedral at Ca(2). Phase 2 crystallizes in a primitive tetragonal cell with a 6.94, c 7.71 Ä; it is probably Ca[Au(OH) 4 ] 2 , but this has not yet been confirmed by a full structure determination.

 Title    Syntheses, Structures, and Spectroscopic Properties of Alkoxide, Hydroxide, and Siloxide Complexes with (r73-Allyl)Mo Moieties  
 Abstract    Salts with binuclear anions of the general formula [(?73-C3H4R)(CO)2Mo(^-OR')2(/i-OR")-Mo(CO)2(f?3-C3H4R) r (R = h , R',R" = Me, 2 ; R = CH3, R' = CH(CH3)2, R" = OH, 3; R = CH3, R' = OH, R" = OSiMe3, 4) have been synthesised via reaction of [(r/3-C3H4R)-Mo(CO)2(CH3CN)2(thf)]+BF4_ , 1, with NaOMe, NaO'Pr, and KOSiMe3. All products were characterised spectroscopically and investigated by single crystal X-ray analysis. In the case of 3 low temperature 2D-NMR spectra revealed that the solid state structure is maintained in solution and that the compound shows a trigonal twist-rearrangement at room temperature.

 Title    Darstellung und Kristallstruktur von Antimon(V)oxidhydroxid HSb308 Preparation and Crystal Structure of the Antimony(V) Oxide Hydroxide HSb30g  
 Abstract    Colourless crystals of HSb3Os were prepared by hydrothermal methods from Sb205. The crystal structure [P2/n, a = 945.6(2), b = 869.1(2), c = 990.9(2) pm, ß = 90.25(2)°, Z = 6. R = 0.045] was determined from diffractometer measurements. Distorted SbOe octahedra are linked through vertices and edges to form a three-dimensional polymer of pseudo-orthorhombic symmetry. The hydrogen atoms could not be located.
