In the title molecule, C5H7N3, intracyclic angles cover the range 117.15 (10)–124.03 (11)°. The N atoms of the amino groups have trigonal–pyramidal configurations deviating slightly from the pyridine plane by 0.106 (2) and −0.042 (2) Å. In the crystal, the pyridine N atom serves as an acceptor of an N—H
N hydrogen bond which links two molecules into a centrosymmetric dimer. Intermolecular N—HN hydrogen bonds between the amino groups further consolidate the crystal packing, forming a three-dimensional network.
