RESUMEN
In the title compound, C(16)H(18)N(4)O(2), the two carbonyl groups are in an anti-periplanar conformation with an O=C-C=O torsion angle of 173.86â (17)°. In the crystal, a pair of inter-molecular N-Hâ¯O hydrogen bonds, forming an R(2) (2)(10) ring motif, connect the mol-ecules into an inversion dimer. The dimers are further linked by N-Hâ¯N and C-Hâ¯π inter-actions, forming a zigzag chain along the b axis.
