title: Bis[eth-yl(2-hydroxy-ethyl)aza-nium] 2,2'-disulfanediyldibenzoate.
abstract: The asymmetric unit of the title salt, 2C(4)H(12)NO(+)·C(14)H(8)O(4)S(2) (2-), contains an eth-yl(2-hydr-oxy)aminium cation and half a 2,2'-disulfanediyldibenzoate anion, with the latter disposed about a twofold axis. The cation is a straight chain with the exception of the terminal hydr-oxy group [the N-C-C-O torsion angle is 66.5 (2)°]. A twisted conformation is found for the anion [the C-S-S-C torsion angle is 91.51 (9)° and the dihedral angle between the rings is 81.01 (4)°]. A supra-molecular chain with base vector [101] and a tubular topology is formed in the crystal structure mediated by charge-assisted O-H⋯O(-) and N(+)-H⋯O(-) hydrogen bonding.
