2,6-Dichloro-N-phenyl-benzamide.

ABSTRACT: There are two independent mol-ecules in the asymmetric unit of the title compound, C(13)H(9)Cl(2)NO, in which the dihedral angles between the phenyl and dichloro-phenyl rings have significantly different values [48.5 (3) and 65.1 (3)°]. In the crystal, the mol-ecules are linked via inter-molecular N-H⋯O hydrogen bonds into chains running parallel to 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 asymmetric unit of N26DCPBA contains two mol-ecules. The bond parameters in N26DCPBA are similar to those in NPBA, N2CPBA, 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.

4-Chloro-N-(2,6-dichloro-phen-yl)benzamide.

Project description:The title compound, C(13)H(8)Cl(3)NO, crystallizes with four mol-ecules in the asymmetric unit. In the mol-ecular structure, the conformations of the central amide -CONH group show a wide range of dihedral angles with respect to the attached aromatic rings (benzoyl and anilino). The dihedral angles between the amide group and the benzoyl ring are 8.1?(3), 4.3?(3), 27.8?(1) and 32.7?(2)° in the four mol-ecules. The amide group is twisted out of the plane of the anilino ring, as shown by the dihedral angles of 85.4?(1), 74.3?(1), 88.1?(1) and 77.6?(1)° in the four mol-ecules. The aromatic rings are oriented at dihedral angles of 86.6?(1), 78.0?(1), 60.3?(1) and 69.8?(1)° in the four mol-ecules. The crystal structure is stabilized via inter-molecular N-H?O hydrogen bonds, aromatic aromatic inter-actions, short Cl?Cl contacts and C-H?Cl hydrogen bonds. Inter-molecular hydrogen bonds connect the mol-ecules into two distinct chains running along the c axis of the crystal. One mol-ecule forms an inversion dimer in which the main inter-actions are ?-? stacking [centroid-centroid distances = 3.749?(1) and 3.760?(1)?Å] and a short Cl?Cl contact of 3.408?(1)?Å.
