In the crystal structure of the title compound, C5H6ClN3, molecules are linked by pairs of N—HN hydrogen bonds, forming inversion dimers. These dimers are linked via N—HN hydrogen bonds, forming a two-dimensional network lying parallel to (100). Inversion-related molecules are also linked via a slipped π–π interaction, with a centroid–centroid distance of 3.5259 (11) Å, a normal separation of 3.4365 (7) Å and a slippage of 0.789 Å.
