N-(2,6-Dimethyl-phen-yl)-4-methyl-benzamide.

ABSTRACT: In the mol-ecular structure of the title compound, C(16)H(17)NO, the two aromatic rings are close to orthogonal to each other [dihedral angle 78.8?(1)°], while the central -NH-C(=O)- amide core is nearly coplanar with the benzoyl ring, forming a dihedral angle of 3.5?(2)°. Inter-molecular N-H?O hydrogen bonds in the crystal structure link the mol-ecules into infinite chains running along the c axis of the crystal, and a C-H?O interaction also occurs.

In the mol-ecular structure of the title compound, C(16)H(17)NO, the two aromatic rings are close to orthogonal to each other [dihedral angle 78.8 (1)°], while the central -NH-C(=O)- amide core is nearly coplanar with the benzoyl ring, forming a dihedral angle of 3.5 (2)°. Inter-molecular N-H⋯O hydrogen bonds in the crystal structure link the mol-ecules into infinite chains running along the c axis of the crystal, and a C-H⋯O interaction also occurs. ...[more]

N-(2,6-Dimethyl-phen-yl)-2-methyl-benzamide.

Project description:In the title mol-ecule, C(16)H(17)NO, the N-H and C=O groups are in the anti-periplanar conformation that has been observed in related compounds. Furthermore, the conformation of the C=O group with respect to the methyl substituent in the 2-methyl-phenyl ring is syn, as has also been observed in related structures. The amide group makes dihedral angles of 50.3?(3) and 64.6?(3)° with the 2-methyl-phenyl and 2,6-dimethyl-phenyl rings, respectively, while the angle between the planes of the two rings is 14.26?(7)°. The mol-ecules are packed into chains via N-H?O hydrogen bonds. An intramolecular C-H?O hydrogen bond is also observed.

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

Project description:The title compound, C(15)H(15)NO, crystallizes with two mol-ecules in the asymmetric unit. The H-N-C=O units are in a trans conformation, similar to that observed in N-(3,4-dimethyl-phen-yl)benzamide, N-(2,6-dichloro-phen-yl)benz-amide and other benzanilides. The central -NHCO- bridging unit is tilted at angles of 17.1?(3) and 16.4?(3)° to the benzoyl ring in the two mol-ecules. The two rings (benzoyl and aniline) are almost orthogonal with respect to each other, making dihedral angles of 86.3?(1) and 86.0?(1)° in the two mol-ecules. N-H?O hydrogen bonds link mol-ecules into infinite chains running along the c axis.

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

Project description:The conformations of the N-H and C=O bonds in the structure of the title compound (N26DMP4CBA), C(15)H(14)ClNO, are anti to each other, similar to that observed in N-phenyl-benzamide, N-(3,4-dimethyl-phen-yl)benzamide, N-(2,6-dichloro-phen-yl)benzamide and other benzanilides. There are three mol-ecules in the asymmetric unit of N26DMP4CBA. The central amide group is tilted with respect to the benzoyl ring by 45.2?(1)° in mol-ecule 1, 21.2?(2)° in mol-ecule 2 and 14.9?(2)° in mol-ecule 3. The dihedral angles between the benzoyl and aniline rings are 39.9?(1), 51.0?(1) and 86.3?(3)° in mol-ecules 1, 2 and 3, respectively. Inter-molecular N-H?O hydrogen bonds link the mol-ecules into infinite chains running along the [101] direction. One xylyl group is disordered over two positions; the site occupancy factors are ca 0.6 and 0.4.
