| The new polychalcogenide Cs4N b2Su was pre pared from the melt. Cs4Nb7Sn is orthorhombic, 0 P68, s.g. Pca2, (N o.29), Z = 4 with a = 13.775(9) Ä , b = 8.043(9) A , c = 18.306(5) A. The crystal structure was determ ined from diffractometer data and refined to a conventional R of 0.052 | | | |

| Darstellung und Kristallstruktur von [Cs4(Dibenzo-18-Krone-6)3](S6)2-2CH3CN Synthesis and Crystal Structure of [Cs4(Dibenzo-18-Krone-6)3](S6)2 * 2 CH3CN | | | | 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. | | | |
