Crystal structure of di-ethyl-ammonium aniline-4-sulfonate anilinium-4-sulfonate.
The title compound, C4H12N+·C6H6NO3S-·C6H7NO3S, consists of an ion pair and a zwitterionic neutral mol-ecule. The cation adopts an extended conformation [C-C-N-C torsion angles = 177.1 (3) and -178.4 (3)°]. In the crystal, the components are linked by N-H⋯O and N-H⋯N hydrogen bonds, generating a three-dimensional network, which is consolidated by weak C-H⋯O inter-actions.
