摘要
<jats:p>The title compound, dimercury(II) divanadium(V) ditellurium(IV) undecaoxide, Hg<jats:sub>2</jats:sub>V<jats:sub>2</jats:sub>Te<jats:sub>2</jats:sub>O<jats:sub>11</jats:sub>, is a new representative within the family of divalent oxovanadato(V)tellurates(IV). The anionic framework is made up of disphenoidal [TeO<jats:sub>4</jats:sub>] polyhedra that are linked by corner-sharing to two neighbouring pyrovanadate units, resulting in chains of six-membered rings propagating parallel to [1\overline{1}0]. 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 [VO<jats:sub>4</jats:sub>] tetrahedra. The anionic chains are connected by interjacent six-coordinate Hg<jats:sup>2+</jats:sup>cations into a three-dimensional framework. The 5<jats:italic>s</jats:italic><jats:sup>2</jats:sup>lone electron pair of the Te<jats:sup>IV</jats:sup>atom is stereochemically active and protrudes into the free space of the chain links.</jats:p>
