The high-pressure form of cadmium vanadate, CdV₂O₆

A new columbite-type modification of CdV₂O₆ has been synthesized at high pressure. It contains zigzag chains of edge-sharing VO₆ octa­hedra. Octa­hedra in adjacent chains share corners and form corrugated layers. Octa­hedrally coordinated Cd atoms, which lie on twofold axes, are situated between the layers.

Pb_2.63Cd₂V₃O₁₂, a cation-deficient garnet-type vanadate

Cation-deficient Pb_2.63Cd₂V₃O₁₂ is the first example of a garnet containing lead and cadmium. The Cd and V atoms fully occupy octa­hedral and tetra­hedral sites, respectively, whereas the Pb atoms partially occupy a dodeca­hedral site. The total Pb and Cd content indicates that vanadium is slightly reduced from the +5 oxidation state.

Synchrotron X-ray study of non­centro­symmetric Tb₃RuO₇ with partial structural disorder

The noncentrosymmetric Tb₃RuO₇ structure has been investigated by synchrotron X-ray single-crystal diffraction, revealing that some Tb atoms occupy disordered positions in the P2₁nb superstructure at room temperature.

Dicalcium hepta­germanate Ca₂Ge₇O₁₆ revised

The crystal structure of Ca₂Ge₇O₁₆ has been redetermined in tetra­gonal symmetry and some comparison is made with Cd₂Ge₇O₁₆ and AB₄O₉ structures having A = Sr, P and Ba, and B = Ge.

Na₆(H₂O)₂₀(V₁₀O₂₈)·4H₂O, a novel polyvanadate(V) with a three-dimensional framework

The novel title polyvanadate(V) contains [V₁₀O₂₈]⁶⁻ anions which lie about inversion centres and have approximate 2/m symmetry and which are linked to [Na₃(H₂O)₁₀]³⁺ cations through two terminal and two μ₂-bridging O atoms. The structure contains three inequivalent Na⁺ cations, two of which form [Na₂(H₂O)₈]_n chains, which are linked via NaO₆ octa­hedra involving the third Na⁺ ion, thus forming a three-dimensional framework.

Potassium gallium hydrogenphosphate fluoride, K₂Ga[H(HPO₄)₂]F₂

The structure of the title compound contains ([Ga{H(HPO₄)₂}F₂]²⁻)_n columns of corner-sharing Ga(F₂O₄) octa­hedra and phosphate tetra­hedra held together in a three-dimensional structure by K⁺ cations and hydrogen bonds.
