title: 2-(Ethyl-sulfin-yl)imidazo[1,2-a]pyridine-3-sulfonamide.
abstract: The supra-molecular structure of the title compound, C(9)H(11)N(3)O(3)S(2), is defined by two inter-molecular hydrogen bonds. Pairs of N-H⋯N hydrogen bonds link the mol-ecules into centrosymmetric dimers and N-H⋯O hydrogen bonds link the dimers into a tubular chain structure running parallel to the a axis.
