[Cover illustration] Cover illustration: A magnified view of the one-dimensional chain of hydrogen bonds of 1-naphthylammonium iodide. Only the C atoms to which the N atoms are attached are shown. The schematic shows the four different hydrogen-bonded rings forming a distorted cube. See Lemmerer, Billing & Robinson [Acta Cryst. (2008), C64, o481-o484].

A non-twinned polymorph of CaTe2O5 from a hydrothermally grown crystal

M. Weil and B. Stöger

Synopsis: The crystal structure of hydrothermally grown CaTe2O5 is made up of undulating 2[infinity][Te2O5]2- layers propagating parallel to (100) with the TeIV atoms in fourfold coordination. Adjacent layers are linked by distorted [CaO7] polyhedra along [100].

Formula: CaTe2O5

Sr, Ba and Cd arsenates with the apatite-type structure

T. Đordevic, S. Sutovic, J. Stojanovic and Lj. Karanovic

Synopsis: The title compounds belong to the apatite family. Suitable single crystals were prepared under hydrothermal conditions. All three structures consist of isolated slightly distorted AsO4 tetrahedra which are bridged by Sr2+ in Sr5(AsO4)3F, by Sr2+/Ba2+ in (Sr1.66Ba0.34)(Ba2.61Sr0.39)(AsO4)3Cl and by Cd2+ in Cd5(AsO4)3Cl0.58(OH)0.42.

Formula: Sr5(AsO4)3F, (Sr1.66Ba0.34)(Ba2.61Sr0.39)(AsO4)3Cl and Cd5(AsO4)3Cl10.58(OH)0.42
