Imidazole-imidazolium picrate monohydrate

The asymmetric unit of the title compound, C(3)H(5)N(2)(+)center dot C(6)H(2)N(3)O(7)(-)center dot C(3)H(4)N(2)center dot H(2)O or H(C(3)H(4)N(2))(2)(+)center dot C(6)H(2)N(3)O(7)(-)center dot H(2)O, contains a diimidazolium cationic unit, one picrate anion and one molecule of water. In the crystal, the components are connected by N-H center dot center dot center dot O, N-H center dot center dot center dot N and O-H center dot center dot center dot O hydrogen bonds, forming a two-dimensional network parallel to (001). In addition, weak intermolecular C-H center dot center dot center dot O hydrogen bonds lead to the formation of a three-dimensional network featuring R(5)(5)(19) rings.
