Disorder in Bis(tetraethylammonium) Bis(μ-sulfido)bis[(1,2,3,4-tetrathiabutane-1,4-diyl-S,S)thiotungstate(V)]

Disorder in the terminal η²-S₄ ligands of the [W₂S₂(μ-S)₂(η²-S₄)₂]²⁻ anions of the title binuclear tungsten–sulfur complex, di-μ-sulfido-1:2κ⁴S-disulfido-1κS,2κS-bis(tetrasulfanediyl)- 1κ²S¹,S⁴;2κ²S^1′,S^4′-ditungsten(V), (Et₄N)₂[W₂S₂(μ-S)₂(η²-S₄)₂], results in two anionic orientations (A and B). In both orientations, the metal center is bonded to five S atoms, with a distorted square-pyramidal coordination polyhedron. The dihedral angle between orientations A and B, defined as that between the basal planes through two bridging and two η²-S atoms of the anion is 9.5 (3)°. The five-membered chelate rings of the anions in A and B display envelope geometry with atoms S9 and S3 at the flaps.
