A linear bridging angle in the pyrovanadate group within the crystal structure of Hg2V2Te2O11

The title compound, dimercury(II) divanadium(V) ditellurium(IV) undecaoxide, Hg₂V₂Te₂O₁₁, is a new representative within the family of divalent oxovanadato(V)tellurates(IV). The anionic framework is made up of disphenoidal TeO₄] polyhedra that are linked by corner‐sharing to two neighbouring pyrovanadate units, resulting in chains of six‐membered rings propagating parallel to 10]. The bridging O atom of the pyrovanadate unit is located on an inversion centre, leading to a staggered conformation and a linear V—O—V angle between the two VO₄] tetrahedra. The anionic chains are connected by interjacent six‐coordinate Hg²⁺ cations into a three‐dimensional framework. The 5s² lone electron pair of the Te^IV atom is stereochemically active and protrudes into the free space of the chain links.
