Polysulfonylamines. XCIII. (1,2-Benzenedisulfonylimido-O)(1,4,7,10-tetraoxacyclododecane-κ⁴O)lithium

In the title complex, [Li(C₆H₄NO₄S₂)(C₈H₁₆O₄)], a square-pyramidal coordination sphere around Li⁺ is formed by the four mutually coplanar O atoms of 12-crown-4 at the basal positions and by one O atom of the anionic ligand, 1,3,2-benzodithiazole 1,1,3,3-tetraoxide(1−), at the apical position. The macrocycle adopts the frequently observed [3333] conformation, approximating to C₄ symmetry.
