Two new phosphate langbeinites, Rb₂YbTi(PO₄)₃ and Rb₂Yb_0.32Ti_1.68(PO₄)₃, investigated at 293 and 150 K

J. C. M. Gustafsson, S. T. Norberg, G. Svensson and J. Albertsson

Synopsis: The structures of Rb₂YbTi(PO₄)₃ and Rb₂Yb_0.32Ti_1.68(PO₄)₃ have been determined at both 293 and 150 K. Both compounds belong to the langbeinite structure type, with mixed Yb/Ti populations in the two crystallographically independent octahedral sites (of symmetry 3). Ytterbium favours one of these sites, where about two-thirds of the Yb atoms are found. The O-atom displacement parameters are large in both compounds at both temperatures.

Formula: Rb₂YbTi(PO₄)₃ and Rb₂Yb_0.32Ti_1.68(PO₄)₃

Two alkali metal chlorites, LiClO₂ and KClO₂

A. I. Smolentsev and D. Yu. Naumov

Synopsis: The lithium chlorite, LiClO₂, and potassium chlorite, KClO₂, structures consist of layers of alkali cations bridged by chlorite anions. The Li⁺ cations are tetrahedrally coordinated by oxygen. The coordination environment of the K⁺ cations involve eight O atoms, which form a distorted cube.
