2,5-Dichloro-N-(3-methyl-phen-yl)benzenesulfonamide.

ABSTRACT: In the title compound, C(13)H(11)Cl(2)NO(2)S, the dihedral angle between the aromatic rings is 76.62 (10)° and the C-S-N-C linkage between the rings adopts a gauche conformation [torsion angle = -51.4 (2)°]. A weak intra-molecular C-H⋯O inter-action closes an S(6) ring. In the crystal, inversion dimers linked by pairs of N-H⋯O hydrogen bonds generate R(2) (2)(8) loops.

N-(2,5-Dichloro-phen-yl)-4-methyl-benzene-sulfonamide.

Project description:In the title compound, C(13)H(11)Cl(2)NO(2)S, the N-C bond in the C-SO(2)-NH-C segment has gauche torsion angles with respect to the S=O bonds. The mol-ecule is bent at the S atom with an C-SO(2)-NH-C torsion angle of 62.1?(2)°. Furthermore, the conformation of the N-H bond is syn to the ortho-chloro group in the adjacent benzene ring. The benzene rings are tilted by 67.8?(1)° relative to each other. The crystal structure features dimers linked by N-H?O hydrogen bonds. An intra-molecular N-H?Cl hydrogen bond is also observed.

2,2-Dichloro-N-(2,5-dichloro-phen-yl)acetamide.

Project description:The conformation of the N-H bond in the title compound, C(8)H(5)Cl(4)NO, is syn to the 2-chloro substituent and anti to the 5-chloro substituent in the aromatic ring. The bond parameters are similar to those in 2,2-dichloro-N-phenyl-acetamide and other acetanilides. In the crystal structure, the mol-ecules are linked into chains through N-H?O hydrogen bonding.

N-(2,5-Dichloro-phen-yl)maleamic acid.

Project description:The asymmetric unit of the title compound, C(10)H(7)Cl(2)NO(3), contains two independent mol-ecules. The mol-ecular conformation of each maleamic unit is stabilized by an intra-molecular O-H?O(carbon-yl) hydrogen bond owing to the anti disposition of the participating entities. The mean planes through the benzene ring and the amido group are inclined at angles of 45.7?(1) and 40.8?(1)° in the two mol-ecules. In the crystal, the independent mol-ecules self-associate via N-H?O hydrogen bonds into zigzag ribbons propagating along the a axis. The ribbons are weakly coupled by C-H?? and C-H?O inter-actions.

N-(2,5-Dichloro-phen-yl)succinamic acid.

Project description:In the title compound, C(10)H(9)Cl(2)NO(3), the conformation of the N-H bond in the amide segment is syn with respect to the ortho-Cl atom and anti to the meta-Cl atom of the benzene ring. In the crystal, inter-molecular O-H?O and N-H?O hydrogen bonds pack the mol-ecules into two types of chains along the a and b axes, respectively, leading to an overall sheet structure. The acid group in the side chain is disordered and was refined using a split model with site-occupation factors of 0.60:0.40.

Project description:In the title compound, C(12)H(9)Cl(2)NO(2)S, the conformation of the N-H bond is syn to the 2-chloro group and anti to the 3-chloro group of the aniline benzene ring. The mol-ecule is bent at the S atom with a C-SO(2)-NH-C torsion angle of 66.4?(2)°. The two rings form a dihedral angle of 73.3?(1)° and an intra-molecular N-H?Cl hydrogen bond occurs. The crystal structure features chains linked by N-H?O hydrogen bonds.

Project description:The conformation of the N-H bond in the structure of the title compound, C(8)H(6)Cl(3)NO, is anti to the C=O bond. The N-H H atom shows close intra-molecular N-H?Cl hydrogen bonds with both the ring Cl atom in the ortho position and the side-chain Cl atom. The mol-ecules crystallize in planes parallel to (221).

N,N'-Bis(2,5-dichloro-phen-yl)isophthalamide.

Project description:The asymmetric unit of the title compound, C(20)H(12)Cl(4)N(2)O(2), contains one half-mol-ecule with a center of symmetry along a C⋯C axis of the central benzene ring. The two C=O groups adopt an anti orientation and the two amide groups are twisted away from the central benzene ring by 27.38 (3) and 27.62 (4)°. The mean planes of the dichloro-substituted benzene rings are twisted by 7.95 (4)° with respect to the benzene ring. The crystal packing is stabilized by weak inter-molecular N-H⋯O inter-actions.
