N-(2-Meth-oxy-phen-yl)-4-methyl-benzene-sulfonamide.

ABSTRACT: In the title compound, C(14)H(15)NO(3)S, the geometry around the S atom of the SO(2) group is distorted tetra-hedral. The meth-oxy- and methyl-substituted aromatic rings are oriented at a dihedral angle of 71.39?(9)°. Inter-molecular N-H?O hydrogen bonds form inversion dimers, which stabilize the crystal structure.

Project description:In the title compound, C(14)H(15)NO(3)S, the dihedral angle between the aromatic rings is 59.39?(14)° and the C-S-N-C torsion angle is -71.4?(2)°. In the crystal, a supra-molecular chain running along the b axis with a C(4) graph set is formed via N-H?O hydrogen bonds.

N-(4-Meth-oxy-phen-yl)benzene-sulfonamide.

Project description:In the title compound, C(13)H(13)NO(3)S, the benzene ring of the benzene-sulfonamide moiety is disordered with an occupancy ratio of 0.56 (3):0.44 (3), the disorder components being twisted at and angle of 21 (1)° to each other. The meth-oxy-benzene group is roughly planar (r.m.s. deviation = 0.0144 Å) and the amide N atom is displaced from this plane by 0.090 (6) Å. The dihedral angles between the meth-oxy-benzene group and the major and minor occupancy components of the disordered benzene ring are 54.6 (4) and 62.9 (5)°, respectively. In the crystal, infinite polymeric chains are formed along [100] due to inter-molecular N-H⋯O hydrogen bonding. Weak C-H⋯π inter-actions are also present in the crystal.

N-(5-Chloro-2-meth-oxy-phen-yl)benzene-sulfonamide.

Project description:In the title compound, C(13)H(12)ClNO(3)S, the dihedral angle between the two aromatic rings is 73.94?(9)°. An intra-molecular C-H?O hydrogen bond occurs. In the crystal, inter-molecular N-H?O hydrogen bonds connect the mol-ecules to centrosymmetric dimers, forming an R(2) (2)(8) ring motif. The packing is consolidated by C-H?O hydrogen bonds and weak ?-? inter-actions [centroid-centroid distances = 3.81?(3) and 3.81?(3)?Å].

N-(4-Acetyl-phen-yl)-4-meth-oxy-benzene-sulfonamide.

Project description:The title compound, C15H15NO4S, was obtained by the condensation of 4-amino-aceto-phenone and 4-meth-oxy-benzene-sulfonyl chloride. The dihedral angle between the benzene rings is 86.56?(9)° and the mol-ecule has an approximate V-shaped conformation. The C atom of the meth-oxy group is roughly coplanar with its attached ring [deviation = 0.177?(3)?Å], as is the methyl C atom of the acetyl group with its ring [deviation = 0.065?(2)?Å]. An intra-molecular C-H?O inter-action generates an S(6) ring. In the crystal, N-H?O and C-H?O hydrogen bonds link the mol-ecules into [010] chains. Weak C-H?? inter-actions are also observed.

N-Benzyl-N-(2-meth-oxy-phen-yl)benzene-sulfonamide.

Project description:In the title mol-ecule, C(20)H(19)NO(3)S, the dihedral angle between the phenyl rings is 48.93?(18)°, and they make dihedral angles of 38.37?(17) and 86.50?(19)° with the benzene ring. A weak intra-molecular C-H?O inter-action might stabilize the mol-ecular conformation. In the crystal, weak ?-? stacking inter-actions between the benzene rings [centroid-centroid distance = 3.774?(2)?Å] may help to establish the packing.

In the extended structure, dimers related by a crystallographic twofold axis are connected by pairs of both N-H⋯O hydrogen bonds and C-H⋯O inter-actions, which generate R 2 (2)(8) and R 2 (2)(14) loops, respectively. A weak aromatic π-π stacking inter-action is also observed [centroid-centroid separation = 3.7305 (3) Å].

N-(3-Meth-oxy-benzo-yl)-2-methyl-benzene-sulfonamide.

Project description:In the title compound, C15H15NO4S, the dihedral angle between the methyl- and meth-oxy-substituted benzene rings is 88.99 (12)°. An intra-molecular C-H⋯O hydrogen bond occurs. In the crystal, adjacent mol-ecules form inversion-related dimers through strong N-H⋯O hydrogen bonds, generating R 2 (2)(8) loops. The dimers are further connected through C-H⋯O inter-actions that form C(8) chains parallel to (001). Mol-ecules are also connected through other C-H⋯O hydrogen bonds along the b axis, forming additional C(8) chains. Two aromatic π-π stacking inter-actions [centroid-centroid separations = 3.6150 (1) and 3.6837 (1) Å] generate a three-dimensional architecture.

N-(3-Eth-oxy-phen-yl)-4-methyl-benzene-sulfonamide.

Project description:In the title compound, C(15)H(17)NO(3)S, the two aromatic rings make a dihedral angle of 69.42?(9)° with each other and the bridging C-N-S-C torsion angle is 65.76?(16)°. Weak intra-molecular C-H?O inter-actions may affect the mol-ecular conformation. Two neighbouring mol-ecules generate a hydrogen-bonded dimer about a center of inversion through a pair of inter-molecular N-H?O inter-actions, forming an R(2) (2)(8) ring motif. Furthermore, two inter-molecular C-H?? inter-actions contribute to the stability of the crystal packing.
