ber Alkali-hexachlorochromate(III): Na3CrCl6

Cs3ScCl6

Crystals of tricaesium scandium(III) hexa­chloride were obtained as a side product from the reaction of U, SnCl₂, Sc, and S in a CsCl flux at 1073 K. Cs₃ScCl₆ crystallizes in the Rb₃YCl₆ structure type. The asymmetric unit comprises three Cs sites, two Sc sites, and six Cl sites, all of which have site symmetry 1, except for the two Sc sites that have site symmetries of 2 and -1, respectively. The structure is composed of isolated [ScCl₆]³⁻ octa­hedra that are surrounded by Cs⁺ cations. Two Cs⁺ cations have inter­actions with eight Cl⁻ anions, while the third has inter­actions with ten Cl⁻ anions.
