Abstract:
The anion of the title compound, C(5)H(6)N(+)·C(5)H(2)NO(4)S(-), is approximately planar, with the carboxyl-ate and nitro group planes forming dihedral angles of 7.5 (3) and 3.5 (3)°, respectively, with the thio-phene ring. In the crystal structure, the cations and anions are linked into a two-dimensional network parallel to (011) by N-H⋯O and C-H⋯O hydrogen bonds.
