Abstract: 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-H...N hydrogen bonds between the amino groups further consolidate the crystal packing, forming a three-dimensional network.
