 Title    Darstellung und thermische Zersetzung von Erdalkalimetall-Carbamoylphospliaten Preparation and Thermal Decomposition of Carbamoylphosphates of Alkaline-earth Metals  
 Abstract    After the formation of carbamoylphosphate through the reaction of KH2PO4 with KNCO in aqueous solution, unreacted phosphate and carbamoylphosphate can be separated by fractional precipitation with barium (first step) and calcium or strontium or barium salt solutions (second step) at low temperatures. The carbamoylphosphates of the alkaline earth metals are decomposed above 100 °C to yield predominantly diphosphates and urea. In aqueous suspensions the decomposition proceeds even at room temperature. -The chemical shifts of the phosphorus atom of the carbamoylphosphate ion between pH 6.5 and 8.2 are given.

 Title    Metallacycloalkane, III [1] Darstellung und Charakterisierung von a.a'-Dipyridyl-Nickelacyclopentan Preparation and Characterisation of a,a'-Bipyridyl-nickelacyclopentane  
 Abstract    The title compound was synthesised from bis-l,5-cyclooctadienenickel, a,a'-bipyridyl and 1,4-dibromobutane in 83% yield and its structure determined by X-ray diffraction (a = 16.600, b = 10.837, c = 14.815 Ä; ß = 153.05°; C2/c, Z = 4; symmetry: C2 with square planar coordinated nickel; Ni-C: 1.949 A). a,a'-Bipyridylnickelcyclopentane reacts with maleic anhydride or methylacrylate under reductive elimination to give cyclobutane in 75 and 57% yield; considerable amounts of butenes are formed, in addition to cyclobutane, upon reaction with borontrifluoride-dibutylether or on thermolysis.

 Title    Further Compounds A3NO3: K3NO3 and Rb3N03  
 Abstract    K3N03 and RbsNOa were prepared by solid state reaction of equimolar mixtures of K2O/KNO2 and Rb20/RbN02, respectively. According to X-ray powder photographs their crystal structures are derived from the perovs-kite structure. K3N03 is isostructural with Na3N03 (a = 521.7 pm, Z = 1), Rb3N03 represents a tetragonally distorted variant with a = 770.5, c = 550.8 pm and Z = 2.

 Title    Ag8SnTe6, ein neuer Vertreter der Argyrodite Ag8SnTe6 -a New Argyrodite  
 Abstract    AggSnTeö has been synthesized by different methods. The Dielectric Absorption Spectra point to a silver ion conductivity. Bei Arbeiten zur dielektrischen Untersuchung des quaternären Ag-Cu-Sn-Te-Systems konnte die Ver-bindung AgsSnTeö erstmals synthetisiert werden. Diese Verbindung ist nach den bisher vorliegenden Daten isotyp zu den schon bekannten argyrodit-analogen Telluriden mit Si und Ge. Nach Arbeiten von Gorochov [1] und anderen Autoren [2, 3] ist im System Ag2Te-SnTe-Te die Verbindung AggSnTee unter deren Bedingungen nicht existent. Es sollte ein Zerfall in mehrere Kom-ponenten wie AgSnTe2, AgzSni-xTe (x < 0,36), Ag5-zTe3 und Ag2Te stattfinden. Das von uns eindeutig als AggSnTee charakteri-sierte Produkt wurde wie folgt dargestellt: Ein stöchiometrisches Gemenge der Elemente (Ag: 99,999%, Sn: 99,999%, Te: 99,99%) wurde in saubersten, getrockneten und vorher evakuierten Quarzampullen eingeschmolzen, danach innerhalb von 24 h auf eine Temperatur von 800 °C geheizt und bei dieser anschließend einen Tag lang gehalten. Nach dem langsamen Abkühlen auf Raumtempera-tur wurde wieder auf diese Temperatur erhitzt, diese einen Tag lang beibehalten und dann innerhalb von zwei Tagen langsam abgekühlt. Das silbriggraue Produkt war gut kristallisiert. Die teilweise stark verwachsenen Kristalle hatten einen oktaedrischen Habitus. Die nach diesem Verfahren synthetisierte Sub-stanz konnte auch mit Spuren Iod als Transport-mittel kristallin erhalten werden (Temperaturen: 820-550 °C substanzseitig). Darüber hinaus gelang es, das nach den oben be-schriebenen Verfahren hergestellte AggSnTee in einer umgebenden B203-Schmelze in offenen Korund-oder Porzellantiegeln an Luft aufzuschmelzen. Zu diesem Zweck wurde innerhalb eines halben Tages auf eine Temperatur von 800 °C aufgeheizt, diese

 Title    Darstellung und Charakterisierung von Berlinerblau-Analoga des Typs Ti[MB(CN)6] Preparation and Characterization of Prussian Blue Analogs of the Type Ti[MB(CN)6]  
 Abstract    Three compounds of the type Ti[MB(CN)6] (MB = Co, Rh, and Ir) have been synthesized and characterized by means of their X-ray diffraction powder patterns, magnetic measurements, infrared, electronic, and X-ray photoelectron spectra. All compounds crystallize in the face-centered cubic system and form a three-dimensional framework of two octahedral coordination units MBC6 and TiN6. Upon the formation of Ti[MB(CN)6] from the corresponding potassium salt, the jz back-donation in the [MD(CN)6]3-moiety is enhanced by the bridge formation through the cyanide ligand.

 Title    Darstellung und Kristallstruktur von Tl 2 TiS 4 : Ein Perthiotitanat(IV) mit i-[TiS 4 2 "]-Ketten Preparation and Crystal Structure of Tl 2 TiS 4 : A Perthiotitanate(IV) with ^-[TiS 4 2 ~]-Chains  
 Abstract    Tl 2 TiS 4 is orthorhombic, space group Pbca, with a = 22.176(7), b = 9.484(4), c = 6.3977(9) A, Z = 8. The crystal structure was solved by direct methods and refined to a conventional R of0.058 for 704 reflections with I^3a(I). The crystal structure is characterized by infinite perthioanions, i-[TiS 4/2 (S 2) 2 -], which are separated by Tl + -cations. The anion chains are built up by distorted octahedra which share two skew edges to form infinite cis-chains running along [001], The two unshared S-atoms of each octahedron are connected via a S —S-single bond of 2.10 A length. The crystal structure is described as a mixed packing of TI-and S-atoms, composed of puckered T1S 2 -layers, in which the Ti-atoms occupy the octahedral interstices. The relationship of the ^-[XiS^ -]-chains to the anionic groups of Cs 2 TiS 3 is discussed.

 Title    Phasenuntersuchungen im System 2 H a -T a S 2-2 H c -M o S 2 Investigations on Phases in the System 2 H a -T a S 2-2 H c -M o S 2  
 Abstract    Ternary phases in the system TaS2-M o S 2 have been obtained by thermal reactions at 1050 °C of binary layered disulfides and N H 4C1 as promotor. Ternary phases Taj_*Mo*S2 exist in the range 0.5 < jc< 0.9. In the range of 0.25 < * < 0.55 the reactions are quantitative and the phase-compositions are determined by the amounts of the starting materials. For x < 0 .2 lT -T a S 2 and for jc> 0.60 2 H c -M o S 2 are contaminating the resulting ternary phases. Ternary phases have been characterized by X-ray powder diffraction and are indexed rhombohedrally on the basis o f a 3 R-structure with metals in trigonal-prismatic coordination. The phases Tal jcMo*S2 with 0.25 < * < 0.55 show a reversible transition of higher order asso­ ciated with a change in the electrical conductivity mechanism. B elow 420 K the phases show semiconductivity while above 460 K metallic conductivity is observed.
