Ethane-1,2-diaminium dipicrate dihydrate.

ABSTRACT: The title compound, C(2)H(10)N(2) (2+)·2C(6)H(2)N(3)O(7) (-)·2H(2)O, crystallizes with a complete picrate anion and half an ethyl-enediammonium dication on a mirror plane, and two half-water mol-ecules (both on a mirror plane) in the asymmetric unit. The N atoms from separate half ethyl-enediammonium dications are in near proximity to a phenolate O atom and two o-NO(2) groups from the picrate anion, which, along with the water mol-ecule 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 inter-molecular inter-actions between symmetry-related water mol-ecules, the half ethyl-enediammonium dication and the picrate anion, forming a three-dimensional supermolecular structure.
