چکیده
The conformation of the N-H bond in the title compound (23DCPCA), C(8)H(6)Cl(3)NO, is syn to both the 2- and 3-chloro substituents in the aromatic ring, similar to the 2-chloro substituent in 2-chloro-N-(2-chloro-phen-yl)acetamide (2CPCA), the 2- and 3-chloro substituents in N-(2,3-dichloro-phen-yl)acetamide (23DCPA) and in 2,2-dichloro-N-(2,3-dichloro-phen-yl)acetamide (23DCPDCA). The bond parameters in 23DCPCA are similar to those in 2-chloro-N-(phen-yl)acetamide, 2CPCA, 23DCPA, 23DCPDCA and other acetanilides. The mol-ecules in 23DCPCA are linked into chains through N-H⋯O hydrogen bonding.
