2,2-Dichloro-N-(3-nitrophenyl)acetamide

Abstract

The conformation of the N—H bond in the structure of the title compound (3NPDCA), C8H6Cl2N2O3, is anti to the meta-nitro group, similar to that in the structures of 2-chloro-N-(3-nitrophenyl)acetamide (3NPCA) and 2,2,2-trichloro-N-(3-nitrophenyl)acetamide (3NPTCA), and the meta-chloro group in 2,2-dichloro-N-(3-chlorophenyl)acetamide (3CPDCA). The geometric parameters of 3NPDCA are similar to those of 2,2-dichloro-N-phenylacetamide, 3CPDCA, 3NPCA, 3NPTCA and other acetanilides. Intermolecular N—H...O hydrogen bonds link the molecules into chains running along the b axis.
