Crystal structure and Hirshfeld surface analysis of 2-chloro-N-(4-methoxyphenyl)acetamide

Abstract

In the title molecule, C9H10ClNO2, the methoxy group lies very close to the plane of the phenyl ring while the acetamido group is twisted out of this plane by 28.87 (5)°. In the crystal, a three-dimensional structure is generated by N—H...O, C—H...O and C—H...Cl hydrogen bonds plus C—H...π(ring) interactions. A Hirshfeld surface analysis of the intermolecular interactions was performed and indicated that C...H/H...C interactions make the largest contribution to the surface area (33.4%).
