Abstract: The conformation of the N-H bond in the title compound, C8H5Cl4NO, is syn to the 3-chloro substituent, in contrast to the anti conformation observed in N-(3,4-dichlorophenyl)acetamide, 2,2-dichloro-N-(3-chlorophenyl)acetamide and 2,2,2-trichloro-N-(3,4-dichlorophenyl)acetamide. The bond parameters in the title compound are similar to those in other acetanilides. The molecules are linked into zigzag chains running along the c axis through N-HO hydrogen bonding.
