RESUMO
In the title mol-ecule, C9H10ClNO2, the meth-oxy group lies very close to the plane of the phenyl ring while the acetamido group is twisted out of this plane by 28.87â (5)°. In the crystal, a three-dimensional structure is generated by N-Hâ¯O, C-Hâ¯O and C-Hâ¯Cl hydrogen bonds plus C-Hâ¯π(ring) inter-actions. A Hirshfeld surface analysis of the inter-molecular inter-actions was performed and indicated that Câ¯H/Hâ¯C inter-actions make the largest contribution to the surface area (33.4%).
RESUMO
In the title mol-ecule, C18H16N2O3, the di-hydro-quinoxaline moiety, with the exception of the N atom is essentially planar with the inner part of the methyl-propano-ate group (CH2-CH2-O) nearly perpendicular to it. In the crystal, inversion dimers formed by C-Hâ¯O hydrogen bonds are connected into oblique stacks by π-stacking and C-Hâ¯π(ring) inter-actions.
