4-Amino-N-(3-meth-oxy-pyrazin-2-yl)benzene-sulfonamide.

ABSTRACT: The overall mol-ecular geometry of the title compound, C(11)H(12)N(4)O(3)S, is bent, with a dihedral angle of 89.24 (5)° between the best planes through the two aromatic rings. Each mol-ecule behaves as a hydrogen-bond donor toward three different mol-ecules, through its amidic and the two aminic H atoms, and it behaves as a hydrogen-bond acceptor from two other mol-ecules via one of its sulfonamidic O atoms. In the crystal, mol-ecules linked by N-H⋯N and N-H⋯O hydrogen bonds form kinked layers parallel to (001), adjacent layers being connected by van der Waals inter-actions.

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

Project description:The asymmetric unit of the title compound, C(13)H(13)NO(3)S, contains two crystallographically independent mol-ecules in which the dihedral angles between the phenyl and benzene rings are 88.16 (12) and 44.50 (12)°. One of the mol-ecules features an intra-molecular N-H⋯O hydrogen bond. In the crystal, the mol-ecules are linked into dimers by pairs of N-H⋯O hydrogen bonds. The dimers are further connected by C-H⋯O and C-H⋯π inter-actions, forming a three-dimensional network.

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.

Project description:The title Schiff base compound, C(14)H(14)N(2)O(3)S, is non-planar, with a dihedral angle of 24.16 (7)° between the benzene rings. In the crystal, N-H⋯O and N-H⋯N hydrogen bonds link the mol-ecules into a layer parallel to (011). Intra- and inter-layer C-H⋯O inter-actions and π-π inter-actions [centroid-centroid distances = 3.8900 (9) and 3.9355 (8) Å] are also present.

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 π-π inter-actions [centroid-centroid distances = 3.81 (3) and 3.81 (3) Å].

Project description: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.

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 π-π stacking inter-actions between the benzene rings [centroid-centroid distance = 3.774 (2) Å] may help to establish the packing.

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⋯π inter-actions are also observed.

2-Chloro-N-(4-meth-oxy-benzo-yl)-benzene-sulfonamide.

Project description:In the title compound, C14H12ClNO4S, the dihedral angle between the aromatic rings is 82.07 (1)° and the dihedral angle between the planes defined by the S-N-C=O fragment and the sulfonyl benzene ring is 82.46 (3)°. In the crystal, the mol-ecules are linked into C(4) chains running along [001] by strong N-H⋯O hydrogen bonds. A C-H⋯O intera-ction reinforces the [001] chains: its graph-set symbol is C(7). The chains are cross-linked into (100) sheets by further C-H⋯O inter-actions as C(6) chains along [001]. The structure also features weak π-π stacking inter-actions [centroid-centroid distances = 3.577 (1) and 3.8016 (1) Å].
