Correspondence e-mail: [email protected] Received 13 June 2007; accepted 18 June 2007 ˚; Key indicators: single-crystal X-ray study; T = 293 K; mean (S–O) = 0.003 A R factor = 0.034; wR factor = 0.080; data-to-parameter ratio = 29.4.

The crystal structure of dicaesium hexaaquacopper(II) bis[sulfate(VI)], Cs2[Cu(H2O)6](SO4)2, has been redetermined from single-crystal X-ray diffraction data. In comparison with the previous refinement based on single-crystal neutron data [Shields & Kennard (1972). Cryst. Struct. Commun. 1, 189– 191], the results show an improved precision and benefit from inclusion of anisotropic displacement parameters for the nonH atoms. The structure is characterized by a mean Cu—O ˚ . The [Cu(H2O)6] octahedron (1 bond length of 2.094 A symmetry) is strongly distorted because of the Jahn–Teller effect, with a calculated distortion parameter  of 0.0054. The Cs+ cation is ninefold coordinated by seven O atoms and two ˚. water molecules, with a mean Cs—O bond length of 3.238 A

The distortion of the [Cu(H2O)6] octahedron was calculated according to Brown & Shannon (1973). A reasonable hydrogen-bonding geometry was obtained after value normalization following the procedure described by Jeffrey & Lewis (1978) and Taylor & Kennard (1983).
