Abstract: The title compound, C4H6N2O, displays two predominant hydrogen-bonding inter­actions in the crystal structure. The first is between the unprotonated imidazole N atom of one mol­ecule and the hy­droxy H atom of an adjacent mol­ecule. The second is between the hy­droxy O atom of one mol­ecule and the imidazole N-H group of a corresponding mol­ecule. These inter­actions lead to the formation of a two-dimnensional network parallel to (10-1). C-H...O inter­actions also occur.
