Description:
The title compound, C16H19N5O, is built up from a planar quinoxalinone ring system linked through a methylene bridge to a 1,2,3-triazole ring, which in turn carries ann-butyl substituent. The triazole ring is inclined by 67.09 (4)° to the quinoxalinone ring plane. In the crystal, the molecules form oblique stacks along thea-axis direction through intermolecular C—HTrz...NTrz(Trz = triazole) hydrogen bonds, and offset π-stacking interactions between quinoxalinone rings [centroid–centroid distance = 3.9107 (9) Å] and π–π interactions, which are associated pairwise by inversion-related C—HDhydqn...π(ring) (Dhydqn = dihydroquinoxaline) interactions. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H...H (52.7%), H...N/N...H (18.9%) and H...C/C...H (17.0%) interactions.
