 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).
