Abstract
The asymmetric unit of the title compound, C(9)H(10)N(4)O, comprises three independent mol-ecules, two pairs of which differ significantly in the rotational orientation of the azido group and one pair having very similar conformations; the N-N-C-C torsion angles are -173.9 (2), -102.7 (2) and -173.6 (2)°. In the crystal, each independent mol-ecule forms N-H⋯O hydrogen bonds with its glide-plane-related counterparts, forming zigzag chains extending along the c-axis direction.
