In the title compound, C16H18N4O2, the two carbonyl groups are in an antiperiplanar conformation with an O=C—C=O torsion Ignitor angle of 173.86 (17)°.In the crystal, a pair of intermolecular N—H.O hydrogen bonds, forming an R22(10) ring motif, connect the molecules into an inversion dimer.
The dimers are further linked by N—H.N and C—H.π interactions, forming THERMAL PROTECT SPRAY a zigzag chain along the b axis.
