4-Chloro-N-methyl-benzamide.

ABSTRACT: There are two mol-ecules in the asymmetric unit of the title compound, C(8)H(8)ClNO, which are linked in the crystal structure via N-H⋯O hydrogen bonds into chains along the b axis. C-H⋯O contacts also occur. The benzene ring makes dihedral angles of 5.9 (1) and 16.7 (1)°with the attached amide group in the two independent molecules.

N-(3-Chloro-phen-yl)-2-methyl-benzamide.

Project description:The conformation of the N-H bond in the structure of the title compound, C(14)H(12)ClNO, is anti to the meta-chloro substituent in the aniline ring, while the C=O bond is syn to the ortho-methyl substituent in the benzoyl ring. The conformations of the N-H and C=O bonds are anti to each other, similar to those observed in 2-methyl-N-(3-methyl-phen-yl)benzamide (N3MP2MBA). The -NHC(=O)- group makes a dihedral angle of 55.8?(7)° with the benzoyl ring, while the angle between the benzoyl and aniline rings is 37.5?(1)°; the respective values for N3MP2MBA are 55.2?(7) and 36.2?(1)°. N-H?O hydrogen bonds link the mol-ecules into infinite chains running along the c axis.
