title: 2,2'-Dimethyl-4,5'-dinitro-1H,3'H-1,4'-biimidazole monohydrate.
abstract: The two almost perfectly planar imidazole rings in the title compound, C8H8N6O4 x H2O, make a dihedral angle of 63.01 (10) degrees . The water molecule acts as a double donor and double acceptor of strong and linear hydrogen bonds, including an exceptionally short C-H...O bond. These bonds create a tight three-dimensional structure and are probably responsible for the relatively high melting point of the compound.
