N-(3,5-Dichloro-phen-yl)benzamide.

ABSTRACT: The conformation of the H-N-C=O unit in the title compound, C(13)H(9)Cl(2)NO, is trans, similar to the conformation observed in N-(3-chloro-phen-yl)benzamide, N-(2,3-dichloro-phen-yl)benzamide, N-(2,4-dichloro-phen-yl)benzamide, N-(2,6-dichloro-phen-yl)benzamide and N-(3,4-dichloro-phen-yl)benz-amide. The amide group makes dihedral angles of 14.3?(8) and 44.4?(4)° with the benzoyl and aniline rings, respectively, while the benzoyl and aniline rings form a dihedral angle of 58.3?(1)°. The mol-ecules are linked by N-H?O hydrogen bonds into infinite chains running along the c axis.

N-(2,6-Dichloro-phen-yl)benzamide.

Project description:The conformation of the N-H and C=O bonds in the structure of the title compound (N26DCPBA), C(13)H(9)Cl(2)NO, are anti to each other, similar to that observed in N-phenyl-benzamide (NPBA), N-(2-chloro-phen-yl)benzamide (N2CPBA), N-(2,3-dichloro-phen-yl)benzamide (N23DCPBA) and other benzanilides.

The amide group, -NHCO-, makes a dihedral angle of 30.8 (1)° with the benzoyl ring in the first mol-ecule and 35.1 (2)° in the second mol-ecule of the asymmetric unit. The dihedral angle between the two benzene rings (benzoyl and aniline) is 56.8 (1)° in the first mol-ecule and 59.1 (1)° in the second mol-ecule. N-H⋯O hydrogen bonds give rise to infinite chains running along the a axis of the crystal structure.
