RESUMO
The quinoxaline moiety in the title mol-ecule, C13H13ClN2O3, is almost planar (r.m.s. deviation of the fitted atoms = 0.033â Å). In the crystal, C-Hâ¯O hydrogen bonds plus slipped π-stacking and C-Hâ¯π(ring) inter-actions generate chains of mol-ecules extending along the b-axis direction. The chains are connected by additional C-Hâ¯O hydrogen bonds. Hirshfeld surface analysis indicates that the most important contributions to the crystal packing are from Hâ¯H (37.6%), Hâ¯O/Oâ¯H (22.7%) and Hâ¯Cl/Clâ¯H (13.1%) inter-actions.
