Barium divanadium(V) tellurite(IV)

A new three-dimensional bimetallic tellurite, BaV₂TeO₈, was synthesized by the hydro­thermal reaction of Ba(OH)₂, TeO₂ and V₂O₅, and characterized by single-crystal X-ray diffraction. The three-dimensional framework is built up from anionic [V₂TeO₈]_n²ⁿ⁻ layers parallel to (101) and connected via Ba—O bonds. The anionic layers are formed by three types of polyhedra, namely VO₅ tetra­gonal pyramids, VO₄ tetra­hedra and TeO₄₊₂ `folded square' polyhedra.

Cerium triiodate, Ce(IO₃)₃

The structure of Ce(IO₃)₃ consists of chains of edge-sharing CeO₉ polyhedra, which are linked into layers by IO₃⁻ groups. The layers are held together via long I⋯O contacts, resulting in a three-dimensional network.

Dilead(II) trimercury(II) tetraoxide chromate(VI), Pb₂(Hg₃O₄)(CrO₄)

Pb₂(Hg₃O₄)(CrO₄) consists of isolated CrO₄²⁻ tetra­hedra and Hg₃O₄²⁻ zigzag chains connected by inter­stitial Pb atoms. The Hg atoms are linearly coordinated by O atoms; the divalent lead ions are coordinated by three close and five more distant neighbours.

Rubidium gadolinium bis­(tungstate)

The structure of rubidium gadolinium bis­(tungstate), RbGd(WO₄)₂, has been determined. The crystal is built up from corner- and edge-sharing WO₆ octa­hedral and GdO₈ polyhedral groups, giving rise to a Gd–WO₄ polyhedral backbone surrounding structural cavities filled with Rb⁺ cations. The Gd and Rb atoms lie on twofold axes.

Hexalithium hexadecahydrate decavanadate, [Li₆(H₂O)₁₆V₁₀O₂₈]_n

The novel title compound, poly­[octa-μ-aqua-octa­aqua-μ-decavanadato-hexalithium], contains [V₁₀O₂₈]⁶⁻ polyanions with 2/m symmetry linked by centrosymmetric [Li₆(H₂O)₁₆]⁶⁺ cation chains to form a two-dimensional network structure.
