Abstract: In the title compound, C₁₆H₁₈N₄·2H₂O, there is one half-molecule (organic) and one water molecule in the asymmetric unit, the organic molecule being centrosymmetric. The separation of the two terminal N atoms is 11.296 (8) Å and the dihedral angle between the benzene and imidazole rings is 85.27 (18)°; the molecule adopts a Z-shaped conformation. A one-dimensional water chain links the organic molecules, forming a two-dimensional ladder-shaped network along the b-axis direction through intermolecular O-HO and N-HO hydrogen bonds.
