Crystal structure and Hirshfeld surface analysis of N,N′-(2,2-di­chloro-3-oxo-3-phenyl­propane-1,1-di­yl)diacetamide

Abstract

In the crystal, mol­ecules are inter­connected by inter­molecular N—H⋯O, C—H⋯O, and C—H⋯Cl inter­actions establishing a three-dimensional network. Furthermore, the mol­ecules form layers parallel to the (002) plane via C—H⋯π inter­actions.

The conformation of the title mol­ecule, C₁₃H₁₄Cl₂N₂O₃, is maintained by intra­molecular N—H⋯O, C—H⋯O, and C—H⋯Cl inter­actions, creating S(6), S(5), and S(6) motifs, respectively. In the crystal, inter­molecular N—H⋯O, C—H⋯O, and C—H⋯Cl inter­actions connect the mol­ecules, forming a three-dimensional network. Additionally, the mol­ecules are linked by C—H⋯π inter­actions, forming layers parallel to the (002) plane. The most important inter­actions, according to Hirshfeld two-dimensional fingerprint plots, are H⋯H (35.0%), O⋯H/H⋯O (21.2%), Cl⋯H/H⋯Cl (20.7%), and C⋯H/H⋯C (17.1%).
