 Title    Darstellung und Kristallstruktur von Cs6Cl40 P rep aratio n and Crystal S tructure of Cs6Cl40  
 Abstract    The solid state synthesis and the crystal struc­ ture of Cs6Cl40 (Pearson-code hR22, R3c, a = 1324.7(6), c -1658(1) pm, Z -6, 931 reflections with I0 > 2a(I), R\ = 0.040, wR2 = 0.114) are repor­ ted. The compound crystallises isotypically with Rb6Cl40 in the anti-K4CdCl6 type of structure. The structure consists of infinite chains of alterna­ ting face-sharing OCs6 octahedra and ClCs6 trigo­ nal prisms which are separated by chloride anions. The underlying structural concept and the ana­ logy to perovskites are outlined.

 Abstract    [Cs4(dibenzo-18-crown-6)3](S6)2-2CH3CN has been prepared from dibenzo-18-crown-6, Cs2C 0 3 and suifur in acetonitrile saturated with H 2S. The title compound crystallizes in space group P I (lattice dimensions: a = 10,507(7)Ä, b = 11,504(6) A, c = 17,792(9) A, a = 97,86(4)°, ß = 105,86(4)°, y = 101,48(5)°) with one formula unit. The crystallographic units are built of stacks of three crown ether molecules and two hexasulfide chains with the cations located between them. The conformation of the hexasulfide chains is all-cis.

 Title    Methanolothermale Synthese von Cs4As2Te6, des ersten Alkalimetall- Telluridoarsenats mit As-As-und Te-Te-Bindungen Methanolothermal Synthesis of Cs4As2Te6, the First Alkali Metal Telluridoarsenate with As-As and Te-Te Bonds  
 Abstract    Reaction of Cs2C 0 3 and As2Te3 in methanol at 145°C affords the telluridoarsenate(II) Cs4As2Te(,. A trans conformation is observed for the centrosymmetric As2Te^~ anions, which consist of two t/>-tetrahedralo As(As)(Te2)Te units with a common As-As bond. The terminal As-Te distance of 2.554(2) A is much shorter than the As-Te distance of 2.691(2) A to the Te2 unit, which exhibits a Te-Te bond length of 2.744(2) A. Both of the independent cations are coordinated in an irregular manner by eight Te atoms.

 Title    Die Kristallstruktur von CsNaTe The Crystal Structure o f CsNaTe  
 Abstract    The crystal structure of CsNaTe has been determined by X-ray diffraction of single crystals. The hygroscopic CsNaTe crystallizes in the tetragonal space group P4/nmm (Z = 2) with the cell parameters a = 527.6(1) and c = 847.8(2) pm. The structure was determined from 237 independent reflections by Patterson and Fourier methods {R] = 0.065; wR2 = 0.080).

Diphenylphosphinic acid amide forms dimeric molecules via N-H- • O hydrogen bonds, the dimeric units again are associated via hydrogen bonds to form infinite double chains along the crystallographic c axis. [Cs{Ph2P(0)NH}]: Space group Pccn, Z = 8 , lattice dimensions (-83°C): a = 1262.8(1), b = 2632.3(2), c = 769.1(1) pm , R\ = 0.024. The compound is associated via Cs-O and Cs-N contacts along the crystallographic [001] axis forming a tubular arrangement. There are no hydrogen bonds.

 Title    Anomalous Temperature Dependence of the "Tc Quadrupole Coupling and Disordering of Cesium Positions in CsTc0 4  
 Abstract    A "Tc and 133 Cs solid-state NMR study of polycrystalline CsTc04 at a field of 7.04 T and temperatures from 90 to 430 K revealed first-order quadrupole effects. "Tc quadrupole coupling constant, Cq, shows anomalous positive temperature coefficients and decreases from 2.0 MHz at 430 K to 0.45 MHz at 90 K. The asymmetry parameter, rj ("Tc), is zero at 430 K and at 210 K. The high-temperature minimum of rj is associated with a phase transition from orthorhombic to tetrag-onal and the second minimum reflects an orientational change of the principal axes q xx and q yy of the EFG-tensor. The 133 Cs NMR spectra are characterised by a superposition of the two powder multiplets from the first-order couplings which arise from magnetically and crystallographically nonequivalent cesium sites, Cs (1) and Cs (2); the population ratio of Cs (2) and Cs (1), p2/p1, varies from 2.0 at 120 K to 6.5 at 373 K. The nonequivalence and population changes are attributed to the temperature change of the crystal field potential in the vicinity of the cations.

 Title    Cesium Determination in Physiological Fluids and Tissues by Field Desorption Mass Spectrometry+  
 Abstract    Quantitative ultratrace analysis (10 nmol to 10 /cmol/1) of cesium in biological samples such as human body fluids and animal tissues is performed without any prior purification or concentration steps. The normal level of cesium ions in heart cells was determined. After poisoning these cells with high concentrations of the alkali cation much higher levels were found inside the cells then had been suggested previously. It is demonstrated that field desorption mass spectrometry is a unique tool for the qualitative and quantitative investigations of metal cations in biological material.
