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-HN hydrogen bonds, forming an inversion dimer with an R₂²(8) ring motif. The dimers are further linked via N-HO hydrogen bonds into an undulating sheet structure parallel to the bc plane.
