Abstract: The title compound, C5H6ClN3O, is essentially planar with a maximum deviation of 0.0256 (11) Å for all non-H atoms. In the crystal, adjacent molecules are linked by a pair of N-H...N hydrogen bonds, forming an inversion dimer with an R22(8) ring motif. The dimers are further linked via N-H...O hydrogen bonds into an undulating sheet structure parallel to the bc plane.
