Abstract
The title compound, C2H10N2 2+·2C6H2N3O7 −·2H2O, 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⋯O, O—H⋯O and weak intermolecular C—H⋯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.
