Fun, H.-K.Yeap, C.S.Rai, S.Isloor, A.M.Shetty, P.2026-02-052010Acta Crystallographica Section E: Structure Reports Online, 2010, 66, 8, pp. o1913-16005368https://doi.org/10.1107/S1600536810025067https://idr.nitk.ac.in/handle/123456789/27429The asymmetric unit of the title compound, C<inf>7</inf>H <inf>10</inf>N<inf>2</inf>O<inf>4</inf>S, comprises of two independent mol-ecules (A and B) which differ in the orientation of the methyl-sulfonyl group [C - S - C - N = 157.98 (13)° in mol-ecule A and 6.09 (18)° in mol-ecule B]. In the crystal structure, mol-ecules of type A are linked into chains along the a axis by inter-molecular C - H?O hydrogen bonds. The B mol-ecules are linked to these chains by C - H?O hydrogen bonds.
