title: 1,2-Bis[2-(2-nitro-1H-imidazol-1-yl)eth-oxy]ethane.
abstract: In the crystal structure, the title compound, C(12)H(16)N(6)O(6), lies on an inversion centre. The mol-ecule has an anti-periplanar 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-(eth-oxy)ethane group is 76.04 (6)°. The mol-ecules are stacked along the c axis through a weak C-H⋯O inter-action and a π⋯π inter-action between the imidazole rings with a centroid-centroid distance of 3.5162 (6) Å. An intramolecular C-H⋯O hydrogen bond is also present.
