Dicaesium hexachlorotantalate(IV), Cs₂TaCl₆

H. Yun and G.-J. Jang

Abstract: Dicaesium hexachlorotantalate(IV), Cs₂TaCl₆, is a new member of the K₂PtCl₆ structure type. The structure consists of a face-centered cubic (fcc) [TaCl₆]^2- anion lattice with Cs⁺ cations occupying the tetrahedral holes. The Ta⁴⁺ ion is octahedrally coordinated by Cl^- ions and the Cs⁺ ion is surrounded by Cl^- ions in a cubooctahedral fashion. The site symmetries of the Cs, Ta, and Cl atoms are 3m, mm, and 4m.m respectively.
