Nickel vanadium tellurium oxide, NiV₂Te₂O₁₀

Single crystals of a nickel vanadium tellurium oxide were synthesized. The crystal structure is layered. The building units are VO₆ and NiO₆ octa­hedra and TeO₄E distorted square pyramids (E being the 5s² lone electron pair of Te^IV).

La(Ni_2/3Nb_1/3)O₃ by neutron powder diffraction

A full analysis of the structure of the double perovskite La(Ni_2/3Nb_1/3)O₃ has been performed for the first time using neutron powder diffraction.

Lithium barium silicate, Li₂BaSiO₄, from synchrotron powder data

The determined structure of lithium barium silicate, Li₂BaSiO₄, consists of two types of tetra­hedra, viz. (SiO₄)⁴⁻ and (LiO₄)⁷⁻, and Ba²⁺ atoms located at the centers of open spaces formed by the tetra­hedra. These tetra­hedra share edges to form (Li₆SiO₁₃)⁵⁻ units. These basic units are connected by sharing corners (O atoms) parallel to [001] and through sharing (SiO₄)⁴⁻ tetra­hedra in (001).

Ba₂Ti₂Si₂O₉F₂, a new titanium silicate

Dibarium dititanium difluoride dioxide hepta­oxidodisilicate, Ba₂Ti₂Si₂O₉F₂, is a new edge-sharing titanate with a unique titanium silicate framework. Titanium oxyfluoride octa­hedra combine with silicon tetra­hedra to form a double stacked chain, which is the base unit of the layered framework.

Ortho­rhom­bic aluminium oxyfluoride, AlOF

Ortho­rhom­bic crystals of aluminium oxyfluoride consist of octa­hedral and tetra­hedral AlF(O)_n blocks with common vertices. Inter­ionic Al—F(O) distances are strictly separated into three groups. The structure differs markedly from the reported tetra­gonal phase Al_1−xO_1−3xF_1+3x (x = 0.0886).
