In the title compound, C6H13N3, the C=N and C-N bond lengths in the CN3 unit are 1.3090 (17), and 1.3640 (17) (C-NH2) and 1.3773 (16) Å, indicating double- and single-bond character, respectively. The N-C-N angles are 116.82 (12), 119.08 (11) and 124.09 (11)°, showing a deviation of the CN3 plane from an ideal trigonal-planar geometry. The piperidine ring is in a chair conformation. In the crystal, molecules are linked by N-HN hydrogen bonds, forming a two-dimensional network along the ac plane.
