Abstract

In the title compound, C10H10N4O2, the dihedral angle between the planes of the pyridine and oxo-pyrroli-dine rings is 6.9 (2)°. In the crystal, inversion dimers linked by pairwise N-H⋯O hydrogen bonds generate R 2 2(14) loops.

Keywords: X-ray crystallography; crystal structure; pyridine-2-carbohydrazide.
