Abstract: In the crystal structure, the title compound, C₁₂H₁₆N₆O₆, lies on an inversion centre. The molecule has an antiperiplanar conformation with respect to the C-C bond of the central ethane unit and the two imidazole rings are parallel to each other. The dihedral angle between the imidazole ring and the mean plane of the C and O atoms of the bis(ethoxy)ethane group is 76.04 (6)°. The molecules are stacked along the c axis through a weak C-HO interaction and a interaction between the imidazole rings with a centroid-centroid distance of 3.5162 (6) Å. An intramolecular C-HO hydrogen bond is also present.
