The molecule of the title compound, C16H17N5O3, is build up from two fused six-membered rings linked to a 1,2,3-triazole ring, which is attached to an ethyl azido-acetate group. The dihydroqinoxalinone portion is planar to within 0.0512 (12) angstrom and is oriented at a dihedral angle of 87.83 (5)degrees with respect to the pendant triazole ring. In the crystal, a combination of intermolecular C-H center dot center dot center dot O and C-H center dot center dot center dot N hydrogen bonds together with slipped pi-stacking [centroid-centroid distance = 3.7772 (12) angstrom] and C-H center dot center dot center dot pi (ring) interactions lead to the formation of chains extending along the c-axis direction. Additional C-H center dot center dot center dot O hydrogen bonds link these chains into layers parallel to the bc plane and the layers are tied together by complementary pi-stacking [centroid-centroid distance = 3.5444 (12) angstrom] interactions. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H center dot center dot center dot H (44.5%), H center dot center dot center dot O/O center dot center dot center dot H (18.8%), H center dot center dot center dot N/N center dot center dot center dot H (17.0%) and H center dot center dot center dot C/C center dot center dot center dot H (10.4%) interactions.
