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

Abstract

The meth­oxy group lies very close to the plane of the phenyl ring while the acetamido group is twisted out of this plane. In the crystal, N—H⋯O and C—H⋯O hydrogen bonds form layers of mol­ecules parallel to the ab plane. The layers are connected by C—H⋯Cl hydrogen bonds and C—H⋯π(ring) inter­actions, forming a three-dimensional structure.

Abstract

In the title mol­ecule, C ₉H ₁₀ClNO ₂, 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%).
