Crystal structure and Hirshfeld surface analysis of ethyl 2-(7-chloro-3-methyl-2-oxo-1,2-di-hydro-quinoxalin-1-yl)acetate
{{output}}
The quinoxaline moiety in the title mol-ecule, C13H13ClN2O3, is almost planar (r.m.s. deviation of the fitted atoms = 0.033 Å). In the crystal, C-H⋯O hydrogen bonds plus slipped π-stacking and C-H⋯π(ring) inter-actions generate chains of mol-ecules extend... ...
