Abstract

The mol-ecule of the title pyridine derivative, C(5)H(7)N(3), shows approximately non-crystallographic C(s) symmetry. Intra-cyclic angles cover the range 117.50 (14)-123.03 (15)°. In the crystal, N-H⋯N hydrogen bonds connect mol-ecules into a three-dimensional network. The closest inter-centroid distance between two π-systems occurs with the c-axis repeat at 3.9064 (12) Å.
