tert-Butyl­ammonium 2,3,4,5-tetra­chloro-6-methoxy­carbonyl­benzoate

In the title compound, C4H12N+·C9H3Cl4O4−, the benzene ring forms dihedral angles of 62.4 (2) and 64.0 (3)°, respectively, with the essentially planar methoxy­carbonyl and carboxyl­ate groups. In the crystal structure, inter­molecular N—H⋯O hydrogen bonds connect anions and cations, forming one-dimensional chains along [010].
