Crystal structure and Hirshfeld surface analysis of 2-amino-3-hy­droxy­pyridin-1-ium 6-methyl-2,2,4-trioxo-2H,4H-1,2,3-oxa­thia­zin-3-ide

The asymmetric unit of the title compound, C(5)H(7)N(2)O(+)·C(4)H(4)NO(4)S(−), contains one cation and one anion. The 6-methyl-2,2,4-trioxo-2H,4H-1,2,3-oxa­thia­zin-3-ide anion adopts an envelope conformation with the S atom as the flap. In the crystal, the anions and cations are held together by N—...

Descripción
Sumario:The asymmetric unit of the title compound, C(5)H(7)N(2)O(+)·C(4)H(4)NO(4)S(−), contains one cation and one anion. The 6-methyl-2,2,4-trioxo-2H,4H-1,2,3-oxa­thia­zin-3-ide anion adopts an envelope conformation with the S atom as the flap. In the crystal, the anions and cations are held together by N—H⋯O, N—H⋯N, O—H⋯O and C—H⋯O hydrogen bonds, thus forming a three-dimensional structure. The Hirshfeld surface analysis and fingerprint plots reveal that the crystal packing is dominated by O⋯H/H⋯O (43.1%) and H⋯H (24.2%) contacts.
