| Synthesis and Crystal Structure of New Ternary Chalcogenides of Group IV Metals: K2ZrS4, Rb2ZrS4, and Rb2HfS4  | | | | Abstract
| The new ternary one-dimensional chain compounds K2ZrS4 , Rb2ZrS4 and Rb2HfS4 were prepared at 350 °C by reacting A2S3 and S with elemental M (A = K, Rb; M = Zr, Hf). They are isostructural, crystallizing in the orthorhombic space group Pbca with Z = 8 . The M atoms are in a distorted octahedral environment of four S2_ anions and one S22~ unit. The structure consists of infinite anionic chains comprised of edge-sharing M S6 octahedra running parallel to the [001] direction separated by the alkali metal cations. The composition of the chain may be formulated as j-,[MS4/ 2 (S2)2 -]. The two crystallographically independent alkali cations are in eight-and ninefold coordination of S atoms. | | | |
