The title compound, dimercury(II) divanadium(V) ditellurium(IV) undecaoxide, Hg 2 V 2 Te 2 O 11 , is a new representative within the family of divalent oxovanadato(V)tellurates(IV). The anionic framework is made up of disphenoidal [TeO 4 ] 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 [VO 4 ] tetrahedra. The anionic chains are connected by interjacent six‐coordinate Hg 2+ cations into a three‐dimensional framework. The 5 s 2 lone electron pair of the Te IV atom is stereochemically active and protrudes into the free space of the chain links.
