4-(4-Nitro-benzene-sulfonamido)pyri-dinium chloride
Abstract:
In the title compound, C(11)H(10)N(3)O(4)S(+)·Cl(-), the benzene ring makes an angle of 89.2 (1)° with the pyridinium ring. The dihedral angle between the nitro group and the benzene ring is 15.7 (1)°. The crystal structure is stabilized by N-H⋯Cl hydrogen bonds.
