| 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. | | | |

| [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. | | | |

| 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. | | | |

| 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). | | | |

| The crystal structures of the monoclinic form of Ph2P(0)NH2 and of its cesium salt, [Cs{Ph2P(0)NH}l have been determined by X-ray methods. Ph2P(0)N H 2: Space group P2,/c, Z = 16, lattice dimensions (-80°C): a = 2530.2(3), b = 858.9(2), c = 2135.5(3) pm, ß = 110.78(1)°, R , = 0.055. 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. | | | |
