title: Ethyl-enediammonium bis-(3,4-dihy-droxy-benzoate) monohydrate.
abstract: In the title compound, C(2)H(10)N(2) (2+)·2C(7)H(5)O(4) (-)·H(2)O, the cation lies on a centre of symmetry. The crystal structure is stabilized by various inter-molecular O-H⋯O and N-H⋯O hydrogen bonds, and by weak π-π stacking inter-actions with centroid-centroid distances between symmetry-related benzene rings ranging from 3.5249 (13) to 3.7566 (14) Å.
