The crystal structures ofN-(4-methyl phenyl)-2,2,2-trichloroacetamide, C9H8Cl3NO (1),N-(2,3-dimethyl phenyl)-2,2,2-trichloroacetamide, C10H10Cl3NO (2) andN-(2-nitro phenyl)-2,2,2-trichloroacetamide, C8H5Cl3N2O3(3) have been determined at room temperature (1):P21/c,a= 9.658(3) Å,b= 20.243(5) Å,c= 11.441(3) Å,β= 103.0(1)°,Z= 8, (2):Pna21a= 19.233(5) Å,b= 5.970(2) Å,c= 20.805(5) Å,Z= 8, (3): P[unk],a= 6.809(3) Å,b= 12.717(6) Å,c= 13.240(6) Å,α= 98.67(2)°,β= 96.14(2)°,γ= 101.47(2)°. The phenyl rings as well as the acetamide group are planar. Their orientation suggests very little strain and hence littleπ-bonding. For (1) substitution by a methyl group at C(4) position in the phenyl ring results in a marked deviation in the C(3)–C(4)–C(5) angle from 120°.
