Cu(Cu0.44Cr4.56)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(Cu0.44Cr4.56)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 MnIIIO6 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 \\overline{1}, \\overline{3}, and 3, respectively. An O-H...O hydrogen bond helps to establish the crystal packing.

Formula: LiMn3(SeO3)2(HSeO3)6
