    Description / Table of Contents: Preparation and Crystal Structure of Rb2Sn3S7 · 2 H2O and Rb4Sn2Se6Rb2Sn3S7 · 2 H2O has been prepared by hydrothermal reaction of SnS2 and Rb2CO3 in an with H2S saturated aqueous solution at 190°C. The crystal lattice contains chain anions ∞1[Sn3S72-] which display both SnS4 tetrahedra and SnS6 octahedra. Methanolothermal reaction of SnCl2 with Se and Rb2CO3 at 145°C leads to the formation of Rb4Sn2Se6 which contains edge-bridged bitetrahedral [Sn2Se6]4- anions.
    Notes: Rb2Sn3S7 · 2 H2O wurde durch hydrothermale Reaktion von SnS2 und Rb2CO3 in einer mit H2S gesättigten wäßrigen Lösung bei 190°C synthetisiert. Das Kristallgitter enthält Kettenanionen ∞1[Sn3S72-], die sowohl SnS4-Tetraeder als auch SnS6-Oktaeder aufweisen. Methanolothermale Reaktion von SnCl2 mit Se und Rb2CO3 bei 145°C führt zur Bildung der Phase Rb4Sn2Se6, die isolierte kantenverknüpfte bitetraedrische Anionen [Sn2Se6]4- enthält.
