In the title compound, C6H10N6O4, the nitroamine –NHNO2 substituent and the C–N=N(→ O) unit of the other substituent of the oxadiazole ring are nearly coplanar with the five-membered ring [dihedral angles = 5.7 (1) and 3.0 (1)°]. The amino group of the –NHNO2 substituent is a hydrogen-bond donor to the two-coordinate N atom of the C—N=N(→ O) unit.
The synthesis required several steps; see: Churakov et al. (1995 ▶); Li et al. (2008 ▶); Mel’nikova et al. (2001 ▶).
