2-tert-Butyl-1-(4-nitro-amino-1,2,5-oxadiazol-3-yl)diazene 1-oxide.

In the title compound, C(6)H(10)N(6)O(4), the nitro-amine -NHNO(2) 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 -NHNO(2) substituent is a hydrogen-bond donor to the two-coordinate N atom of the C-N=N(→ O) unit.
