Abstract
Rb2Sn3S7 . 2H2O has been prepared by hydrothermal reaction of SnS2 and Rb2CO3 in an with H2S saturated aqueous solution at 190-degrees-C. Th e crystal lattice contains chain anions 1infinity[Sn3S72-] which displ ay both SnS4 tetrahedra and SnS6 octahedra. Methanolothermal reaction of SnCl2 with Se and Rb2CO3 at 145-degrees-C leads to the formation of Rb4Sn2Se6 which contains edge-bridged bitetrahedral [Sn2Se6]4- anions .
