Abstract

In the title compound, C₁₅H₁₀Cl₃NO ₂, an intra-molecular N - H⋯O hydrogen bond forms a six-membered ring and enforces an almost coplanar conformation for the acetamido group, the central benzene ring and the bridging carbonyl C - C(=O) - C group: the dihedral angles between the benzene ring and the acetamide and carbonyl C - C(=O) - C planes are 7.06 (11) and 7.17 (12)°, respectively. The dihedral angle between the two benzene rings is 67.43 (9)°. Because a strong hydrogen-bond donor is involved in the intra-molecular inter-action, the crystal packing is determined by weak C - H⋯O and C - H⋯Cl interactions.
