The title compound, C4H10N2O, crystallizes with two independent molecules in the space group Cmc21. The first molecule lies in a crystallographic mirror plane with x = 0, whereas the second molecule lies on a general position with x ≃ 
. Each molecule forms classical N—H
O=C hydrogen bonds, thereby leading to chains of molecules parallel or antiparallel, respectively, to the polar c axis.
. Each molecule forms classical N—HO=C hydrogen bonds, thereby leading to chains of molecules parallel or antiparallel, respectively, to the polar c axis.
