The asymmetric unit of the title salt, 2C(2)H(8)NO(+)·C(8)H(4)O(4) (2-), comprises one crystallographically independent 2-hy-droxy-ethanaminium cation and one half terephthalate anion. In the crystal, hydrogen bonds involving the hy-droxy and ammonium groups of the cations and the carboxyl-ate O atoms of the terephthalate anions result in the formation of a three-dimensional network structure.
