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-HO interactions also occur.
