2-Azido- N -(4-methyl-phen-yl)acetamide.

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.
