Polysulfonylamines. XCVIII. 1,2-Benzenedisulfonylamine Acetonitrile Solvate (1/1)

In the 1:1 acetonitrile solvate of 1,3,2-benzodithiazole-1,1,3,3-tetrone, C₆H₅NO₄S₂.C₂H₃N, the nitrile molecule is linked to the NH function by a slightly bent N—H...N hydrogen bond of medium strength [H...N 1.99 (3) and N...N 2.834 (3) Å]. One methyl H atom forms a three-centre C—H...O bond to different symmetry-related formula units. The five-membered heterocycle possesses an envelope conformation, the N atom deviating by 0.358 (2) Å from the mean plane of the C₆S₂ moiety.
