The title compound, C2H10N22+center dot 2C(6)H(2)N(3)O(7)(-)center dot 2H(2)O, crystallizes with a complete picrate anion and half an ethylenediammonium dication on a mirror plane, and two half-water molecules (both on a mirror plane) in the asymmetric unit. The N atoms from separate half ethylenediammonium dications are in near proximity to a phenolate O atom and two o-NO2 groups from the picrate anion, which, along with the water molecule form N-H center dot center dot center dot O, O-H center dot center dot center dot O and weak intermolecular C-H center dot center dot center dot O hydrogen bonds that create cyclic patterns with graph-set descriptors R-2(4)(8), R-4(4)(12), and R-4(4) (16). The crystal packing is strongly influenced by these intermolecular interactions between symmetry-related water molecules, the half ethylenediammonium dication and the picrate anion, forming a three-dimensional supermolecular structure.
