RESUMO
The cup-shaped conformation of the title mol-ecule, C21H22N2O4, is largely determined by an intra-molecular N-Hâ¯O hydrogen bond. In the crystal, double layers of mol-ecules are formed by O-Hâ¯O and C-Hâ¯O hydrogen bonds. A Hirshfeld surface analysis was performed, which confirms the regions that are active for inter-molecular inter-actions.
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%).
