The molecule of the title pyridine derivative, C(5)H(6)N(2)O, shows approximate C(s) symmetry. Intra-cyclic angles cover the range 118.34 (10)-123.11 (10)°. In the crystal, O-H⋯N, N-H⋯O and N-H⋯N hydrogen bonds connect the mol-ecules into double layers perpendicular to the a axis. The shortest centroid-centroid distance between two π-systems is 3.8887 (7) Å. ...[more]
