Ba₆V₄O₅S₁₁

Hexabarium tetravanadium pentaoxide undecasulfide, Ba₆V₄O₅S₁₁, contains isolated VS₄^3-, VOS₃^3-, and VO₂S₂^3- tetrahedra separated by Ba²⁺ ions. The V-S and V-O bond distances are in the range 2.102 (5)-2.175 (3) Å and 1.682 (9)-1.722 (7) Å, respectively. The shortest V-S distances are associated with the VS₄^3- tetrahedra whereas the longest V-S distances are found in the VO₂S₂^3- tetrahedra.
