N-{4-[(3-Methyl-phen-yl)sulfamo-yl]phen-yl}benzamide.

ABSTRACT: In the title compound, C(20)H(18)N(2)O(3)S, the dihedral angle between the central benzene ring and the amide group is 24.1?(3)° and that between this ring and the aromatic ring of the tolyl group is 68.2?(16)°. In the crystal, adjacent mol-ecules are linked by N-H?O hydrogen bonds into a linear chain running along [100]. Weak C-H?O contacts also occur. Extensive weak ?-? inter-actions exist from both face-to-face and face-to-edge inter-actions occur between the aromatic rings [centroid-centroid distances = 3.612?(2) and 4.843?(2)?Å].

Project description:In the title compound, C(17)H(15)N(3)O(4)S, the five-membered isoxazole ring makes dihedral angles of 80.5 (2) and 81.3 (2)° with the two benzene rings, which form a dihedral angle of 39.81 (18)° with each other. A short intra-molecular C-H⋯O contact occurs. The crystal structure is stabilized by inter-molecular N-H⋯O hydrogen bonds, which generate [001] chains, and further consolidated by weak C-H⋯O inter-actions.

N-{4-[(4-Methyl-phen-yl)sulfamo-yl]phen-yl}acetamide.

Project description:The title mol-ecule, C(15)H(16)N(2)O(3)S, has a twisted U-shaped conformation. The twist occurs in the central C-S(=O)(2)N(H)-C unit with the C-S-N-C torsion angle being -58.38?(14)°. The benzene rings lie to the same side of the mol-ecule and form a dihedral angle of 67.03?(10)°. The crystal packing features N-H?O hydrogen bonding, which leads to supra-molecular chains with a tubular topology along the b axis. Intra-molecular C-H?O inter-actions are also observed.

N-(4-Methyl-phen-yl)benzamide.

Project description:The structure of the title compound, C(14)H(13)NO, resembles those of N-(2-chloro-phen-yl)benzamide, 2-chloro-N-phenyl-benzamide, N-(2,3-dichloro-phen-yl)benzamide, N-(3,4-dichloro-phen-yl)benzamide and 2-chloro-N-(2-chloro-phen-yl)benzamide with similar bond parameters. The benzene and methylphenyl rings have a dihedral angle of 63.41?(5)°, while the amide group makes a dihedral angle of 20.5?(1)° with the benzene ring. The mol-ecules are linked into chains in the b-axis direction by N-H?O hydrogen bonds.

N-(3-Methyl-phen-yl)benzamide.

Project description:The asymmetric unit of the title compound, C(14)H(13)NO, contains four mol-ecules, which are linked through N-H⋯O hydrogen bonds into two symmetry-independent chains running parallel to [001] and [101]. The N-H and C=O bonds of the amide groups are trans oriented in all four mol-ecules. The mol-ecules are not planar and both aromatic rings are twisted strongly relative to the plane of the amide group. The dihedral angle between the two benzene rings ranges from 70.6 (2) to 74.2 (2)°. The N-H bond is anti to the meta-methyl substituent in the aniline fragment in three of the four symmetry-independent mol-ecules. In the fourth mol-ecule, the aniline unit is disordered over two nearly coplanar positions; the anti and syn conformers occupy the same site in the crystal with equal probability.
