| Tl2Sn2S5, a Thallium(I) Thiostannate(IV) with Fivefold Coordinated Tin  | | | | Abstract
| The new compound Tl2Sn2Ss was prepared by fusion of a stoichiometric mixture of the elements followed by prolonged heating at 300 °C. The compound crystallizes in the monoclinic system in space group C2/c with lattice constants a — 11.115(2), 6 = 7.723(1), c = 11.492(2) A, and ß = 108.60(1)° (Z = 4). The Sn atoms are coordinated by five S atoms forming a considerably distorted trigonal bipyramid (mean distance Sn-S: 2.497 Ä). By common edges the SnSö bipyramids are linked into chains extending in the [110] and [1T0] directions, respectively. The chains are cross-linked by sharing the remaining equatorial vertices of the SnSs bipyramids, thus forming a three-dimensional framework which is related to that described for NajS^Sg [1]. The T1 atoms located in channels running parallel to the b axis are surrounded by nine S atoms. The distances Tl-S vary from 3.073 to 3.897 A. | | | |
