 Title    Zur Kristallstruktur von Ho2Se3 On the Crystal Structure of Ho2Se3  
 Abstract    Starting from HoSe2_ t powder and holmium metal bright brownish-yellow, plate-like single crystals of Ho2Se3 could be prepared by chemical transport with A1C13. Holmium sesquiselenide crystallizes in the Sc2S3-type structure, space group Fddd, with lattice constants a = 1140,7(2), b -812,6(1) and c = 2423,9(3) pm.

 Title    Synthese und chemischer Transport ternärer Verbindungen, untersucht am Beispiel CoO + Nb205 = CoNb206 Synthesis and Chemical Transport of Ternary Compounds, Investigated with CoO + Nb205 = CoNb206  
 Abstract    Chemical transport reactions (1273 -> 1073 K) with CoO, Nb205 or CoNb206 using TeCl4 as transport agent have been made. The experimental results are compared with thermo-dynamic calculations. General rules for the treatment of chemical transport calculations concerning ternary compounds are given.

 Title    Thermisches Verhalten von festem LaAlCl6 und chemischer Transport von LaCl3 mit AICI3 Thermical Behaviour of Solid LaAlCl6 and Chemical Transport of LaCl3 with A1C13  
 Abstract    The thermodynamical data of solid aluminium lanthanum chloride LaAlCl6 have been ob­ tained by determination of the decomposition equilibria from total pressure measurements. The melting diagram was determined by DTA. The chemical transport of LaCl3 with A1C13 is suggesting the existence of the gaseous complex LaAl3C l12. The data are: Z\H(LaAlCl6 f 298) =-427,1 ±2,5 kcal/mol, S°(LaAlCl6.f.298) = 61 ±2,5 cal/K-mol, _AH(LaAl3C l12 g 298) =-712 ± 7 kcal/mol, S°(LaAl3C l12>g,298) = 205 ± 3 cal/K-mol.

 Title    an FeNblx029, FeNb29074 und TiNb14037 Contributions to the Study of Inorganic Non-Stoichiometric Compounds, V* Preparation and Electron Optical Investigation of FeNbn029, FeNb29 0 74 and TiNb14037  
 Abstract    FeNbn029(m), FeNbn029(o) and two mixed oxides with the composition limits FeNb29074 and TiNbi4037 were prepared by chemical transport. The crystal structures of the compounds have been examined by two-dimensional high resolution electron-micro-scopy. They are composed of 'blocks' of (n x 3) corner shared octahedra and belong to a series of structure related compounds with the general formula Me3nOsra-3-Crystallo-graphic defects and the thermic behavior of the materials are discussed.

 Title    Beiträge zur Untersuchung anorganischer nichtstöchiometrischer Verbindungen, IX a Elektronenmikroskopische Untersuchungen an Kristallen aus Transportexperimenten -System Nb205-W03 (I) Contributions to the Study of Inorganic Non-Stoichiometric Compounds, IX a Electron Microscopical Investigations on Crystals Prepared by Chemical Transport in the System Nb205-W03 (I)  
 Abstract    Compounds near the composition Nb205: WO3 ~ 6:1 were prepared by chemical trans-port (at relatively low temperatures). The block structures of the obtained samples were investigated by high resolution electron microscopy. Besides unusual defects microdomains were found which still contain edgesharing blocks even at the composition 0/27Me = 2.53 to 2.55.
