4-Fluoro-N-methyl-N-(1,2,3,4-tetra-hydro-carbazol-3-yl)benzene-sulfonamide.

ABSTRACT: In the title compound, C(19)H(19)FN(2)O(2)S, the hydrogenated six-membered ring of the carbazole unit adopts a half-chair conformation and the plane of the fluoro-phenyl ring forms a dihedral angle of 41.5?(1)° with respect to the carbazole mean plane. The crystal structure is segregated into layers containing the carbazole units and fluoro-phenyl rings in alternate (200) planes. The carbazole units form centrosymmetric face-to-face inter-actions [inter-planar separation = 4.06?(1)?Å] and edge-to-face inter-actions in which the N-H group is directed towards an adjacent carbazole face, with a shortest H?C contact of 2.53?Å. The fluoro-phenyl rings form face-to-face contacts with an approximate inter-planar separation of 3.75?Å and a centroid-centroid distance of 4.73?(1)?Å.

1,2,3,4-Tetra-hydro-isoquinoline-2-sulfonamide.

Project description:The title compound, C(9)H(12)N(2)O(2)S, is a useful precursor of a variety of modified sulfonamide mol-ecules. Due to the importance of these mol-ecules in biological systems (antibacterials, antidepressants and many other applications), there is a growing inter-est in the discovery of new biologically active compounds. In the title compound, the mol-ecules are linked by N-H?O inter-molecular hydrogen bonds involving the sulfonamide function to form an infinite two-dimensional network parallel to the (001) plane.

Crystal structures of N-(3-fluoro-benzo-yl)benzene-sulfonamide and N-(3-fluoro-benzo-yl)-4-methyl-benzene-sulfonamide.

Project description:The crystal structures of two N-(aryl-sulfon-yl)aryl-amides, namely N-(3-fluoro-benzo-yl)benzene-sulfonamide, C13H10FNO3S, (I), and N-(3-fluoro-benzo-yl)-4-methyl-benzene-sulfonamide, C14H12FNO3S, (II), are described and compared with related structures. The dihedral angle between the benzene rings is 82.73 (10)° in (I) compared to 72.60 (12)° in (II). In the crystal of (I), the mol-ecules are linked by C-H⋯O and C-H⋯π inter-actions, resulting in a three-dimensional grid-like architecture, while C-H⋯O inter-actions lead to one-dimensional ribbons in (II). The crystals of both (I) and (II) feature strong but non-structure-directing N-H⋯O hydrogen bonds with R 2 (2)(8) ring motifs. The structure of (I) also features π-π stacking inter-actions.

Project description:In the title mol-ecule, C(13)H(13)FN(2)OS, the heterocyclic ring adopts a slightly distorted flattened boat conformation, and the plane through the four coplanar atoms makes a dihedral angle of 87.45?(14)° with the benzene ring. The thione, acetyl and methyl groups lie on the opposite side of the heterocyclic mean plane to the fluorophenyl group, which has an axial orientation. N-H?O, N-H?S, C-H?F and C-H?O inter-molecular hydrogen bonds and a weak C-H?? inter-action involving the benzene ring are found in the crystal structure.

trans-rac-[1-Oxo-2-phenethyl-3-(2-thien-yl)-1,2,3,4-tetra-hydro-isoquinolin-4-yl]methyl 4-methyl-benzene-sulfonate.

Project description:The title compound, C(29)H(27)NO(4)S(2), was synthesized by reaction of trans-rac-4-(hydroxy-meth-yl)-2-phenethyl-3-(thio-phen-2-yl)-3,4-dihydro-isoquinolin-1(2H)-one and 4-methyl-benzene-1-sulfonyl chloride in the presence of Et(3)N in CH(2)Cl(2). The relative orientations of the benzene ring (A) of the 3,4-dihydro-isoquinolinone ring system, the thio-phene ring (B), the benzene ring (C) of the methyl-benzene group and the phenyl ring (D) result in the following dihedral angles: A/B = 80.91?(16), A/C = 22.79?(18), A/D = 9.9?(2), B/C = 80.73?(19), B/D = 88.9?(2) and C/D = 29.9?(2)°.

2-[(1Z)-(9-Ethyl-9H-carbazol-3-yl)methyl-eneamino]-4,5,6,7-tetra-hydro-1-benzothio-phene-3-carbonitrile-benzene (2/1).

Project description:In the title compound, 2C(24)H(21)N(3)S·C(6)H(6), the two independent Schiff base mol-ecules (A and B) in the asymmetric unit differ in the orientation of the tetra-hydro-benzothio-phene ring system with respect to the carbazole ring system by 180° rotation about the C-C bond in the C-C=N-C linkage. The two mol-ecules also differ in the orientation of the ethyl groups [C-N-C-C torsion angle of 90.7?(3)° in mol-ecule A, and -79.4?(3)° in mol-ecule B]. In mol-ecule B, two methyl-ene C atoms of the cyclo-hexene ring are disordered over two sites with occupancies of 0.58?(1) and 0.42?(1). The cyclo-hexene rings in both mol-ecules adopt half-chair conformations. The dihedral angle between the thio-phene ring and the carbazole ring system is 8.07?(9)° in mol-ecule A [3.10?(9)° in mol-ecule B]. In the crystal structure, the independent mol-ecules are linked into dimers by inter-molecular C-H?N hydrogen bonds. In addition, C-H?? inter-actions are observed.
