Cu(Cu_0.44Cr_4.56)Ge₂O₁₂: a close-packed oxide with CuO₄ tetrahedra

G. J. Redhammer, G. Roth and G. Amthauer

Synopsis: The structure of the title compound is described as a cubic close-packed arrangement of O atoms containing Cu⁺/Cu²⁺ ions in a tetrahedral coordination. Slabs of edge-sharing CrO₆ octahedra and isolated CuO₄ and GeO₄ tetrahedra are aligned parallel to the bc plane and are separated from each other by GeO₄ tetrahedra along a.

Formula: Cu(Cu_0.44Cr_4.56)Ge₂O₁₂

A pseudo-merohedrally twinned rare-earth sulfate: K₆[Ce(HSO₄)₂(SO₄)₄]·H₂O, a novel structure type

B. M. Casari and V. Langer

Synopsis: This acidic ternary rare-earth sulfate is unique as it contains rare-earth monomers, [Ce(HSO₄)(SO₄)₄]^5-, and the structure is composed of these monomers, water molecules, discrete hydrogensulfate ions and potassium ions held together by ionic interactions. There are two alternating layers in the structure, with the compositions [K₄Ce(HSO₄)(SO₄)₄]^- and [K₂(HSO₄)(H₂O)]⁺.

Formula: K₆[Ce(HSO₄)₂(SO₄)₄]·H₂O

LiMn₃(SeO₃)₂(HSeO₃)₆

M. G. Johnston and W. T. A. Harrison

Synopsis: The title compound, lithium trimanganese bis[trioxoselenate(IV)] hexakis[hydrogentrioxoselenate(IV)], is built up from a vertex-sharing network of distorted Mn^IIIO₆ octahedra, SeO₃ and HSeO₃ pyramids, and unusual Li(OH)₆ octahedra, resulting in a dense three-dimensional structure. Mn, Li and one Se atom have site symmetries of , , and 3, respectively. An O-HO hydrogen bond helps to establish the crystal packing.
