Crystal structure and Hirshfeld surface analysis of ethyl 2-{4-[(3-methyl-2-oxo-1,2-di-hydro-quinoxalin-1-yl)meth-yl]-1H-1,2,3-triazol-1-yl}acetate.

ABSTRACT: The mol-ecule 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 di-hydro-qinoxalinone portion is planar to within 0.0512 (12) Å and is oriented at a dihedral angle of 87.83 (5)° with respect to the pendant triazole ring. In the crystal, a combination of inter-molecular C-H⋯O and C-H⋯N hydrogen bonds together with slipped π-stacking [centroid-centroid distance = 3.7772 (12) Å] and C-H⋯π (ring) inter-actions lead to the formation of chains extending along the c-axis direction. Additional C-H⋯O hydrogen bonds link these chains into layers parallel to the bc plane and the layers are tied together by complementary π-stac
