U. Kolitsch

Abstract: The title compound, dicaesium trichromium(VI) oxide, is the orthorhombic (space group Pbca) modification of Cs₂Cr₃O₁₀. The compound is isotypic with its NH₄ and Rb trichromate analogues. The structure contains discrete [Cr₃O₁₀]^2- anions [Cr-O-Cr = 136.58 (11) and 140.30 (12)°] linked via two non-equivalent irregularly 11-coordinated Cs⁺ cations [d_av(Cs-O) = 3.224 and 3.272 Å]. All atoms are in general positions.
