DISORDER IN BIS(TETRAETHYLAMMONIUM) BIS(MU-SULFIDO)BIS 3,4-TETRATHIABUTANE-1,4-DIYL-S,S)THIOTUNGSTATE(V)]

Disorder in the terminal eta(2)-S-4 ligands of the [W2S2(mu-S)(2)(eta( 2)-S-4)(2)](2-) anions of the title dinuclear tungsten-sulfur complex, di-mu-sulfido-1:2 kappa(4)S-disulfido-1 kappa S,2 kappa S-bis(tetrasu lfanediyl)-1 kappa(2)S(1),S-4;2 kappa(2)S(1)':S-4'-ditungsten(V), (Et( 4)N)(2)[W2S2(mu-S)(2)(eta(2)-S-4)(2)], results in two anionic orientat ions (A and B). In both orientations, the metal center is bonded to fi ve S atoms, with a distorted square-pyramidal coordination polyhedron. The dihedral angle between orientations A and B, defined as that betw een the basal planes through two bridging and two eta(2)-S atoms of th e anion, is 9.5(3)degrees. The five-membered chelate rings of the anio ns in orientations A and B display envelope geometry, with atoms S9 an d S3 at the flaps.
