4-Methyl-9-[(4-methyl-phen-yl)sulfon-yl]thio-pyrano[3,4-b]indole-3(9H)-thione.

ABSTRACT: The title compound, C(19)H(15)NO(2)S(3), is the first example of a dithia analogue of pyrano[3,4-b]indolone. The almost planar thio-pyrano-indole-thione ring system (r.m.s. deviation for all non-H atoms = 0.030 Å) makes a dihedral angle of 80.70 (8)° with the p-tolyl ring. In the crystal, mol-ecules are connected via C-H⋯O hydrogen bonds into two chains along the b axis. These chains are connected via π-π inter-actions between symmetry-related thio-pyrano-indole-thione ring systems [centroid-centroid distance = 3.588 (1) Å].

Project description:Rhodium-catalyzed [2+2+2] cyclo-addition of carbon di-sulfide to o,N-dialkynyl-tosyl-anilines gives two isomeric indolo-thio-pyran-thio-nes, a violet and a red isomer. This is the first crystal structure of a red isomer, which crystallizes with one solvent mol-ecule of di-chloro-methane in the asymmetric unit, C24H17NO2S3·CH2Cl2. In the extended structure, centrosymmetric pairs of the planar annulated system are arranged in strands and solvent mol-ecules fill the space between the strands.

5-(4-Chloro-phen-yl)-1-methyl-3-phenyl-3,6,8,9-tetra-hydro-pyrazolo-[3,4-b]thio-pyrano[4,3-d]pyridine.

Project description:The title compound, C(22)H(18)ClN(3)S, was synthesized by the reaction of 4-chloro-benzaldehyde, tetra-hydro-thio-pyran-4-one and 3-methyl-1-phenyl-1H-pyrazol-5-amine in acetic acid without a catalyst. The pyridine and pyrazole rings are almost coplanar, the dihedral angle between their mean planes being 2.50 (1)°. The thio-pyran ring exhibits an envelope conformation. The crystal packing is stabilized by inter-molecular C-H⋯Cl hydrogen bonds and by C-H⋯π and π-π inter-actions [centroid-centroid distances of 3.825 (2) Å between pyridine rings and 3.557 (2) Å between pyrazole and pyridine rings.

Project description:In the title indole derivatives, C22H16N2O5S, (I) and C20H15NO3S2, (II), the sulfonyl-bound phenyl rings are almost orthogonal to the indole ring system, subtending dihedral angles of 88.33 (10) and 87.58 (16)°, respectively. In both compounds, the sulfonyl S atom has a distorted tetra-hedral geometry [O-S-O = 119.98 (9) and N-S-C = 104.01 (8)° for compound (I) and O-S-O = 120.08 (18) and N-S-C = 104.91 (14)° for compound (II)] and the sum of the bond angles at N indicates sp2 hybridization. The mol-ecules of both (I) and (II) feature intra-molecular C-H⋯O hydrogen bonds that generate S(6) ring motifs with the sulfone O atom. In the crystals, mol-ecules of (I) are linked by C-H-O hydrogen bonds, forming R44(18) ring motifs while mol-ecules of (II) are linked by C-H-O and C-H-S hydrogen bonds, forming R22(12) ring motifs.

Project description:In the title compound, C(14)H(13)N(3)OS(2), the thio-phene ring is disordered over two orientations by ca 180° about the C-C bond axis linking the ring to the rest of the mol-ecule, with a site-occupancy ratio of 0.651 (5):0.349 (5).

In the crystal, no significant inter-molecular hydrogen bonds are observed. The crystal packing is stabilized by π-π inter-actions [centroid-centroid distance = 3.589 (2) Å].

The crystal packing is dominated by C-H⋯O contacts and π-π inter-actions [ring centroid distance = 3.6902 (12) Å].

2-(4,5-Di-chloro-2-nitro-phen-yl)-4-meth-oxy-3-methyl-9-phenyl-sulfon-yl-9H-carbazole.

Project description:In the title compound, C26H18Cl2N2O5S, the carbazole ring system is essentially planar with a maximum deviation of 0.0498 (16) Å for the N atom. The carbazole ring system is almost orthogonal to the phenyl-sulfonyl and di-chloro-substituted nitro-phenyl rings, making dihedral angles of 84.23 (7) and 85.46 (12)°, respectively. The mol-ecular structure features intra-molecular C-H⋯O inter-actions, which generate two S(6) ring motifs. In the crystal, mol-ecules are linked by C-Cl⋯O halogen bonds [3.016 (3) Å, 166.63 (5)°], which generate infinite C(8) chains running parallel to [010].

Methyl 4-{[(4-methyl-phen-yl)sulfon-yl]amino}-benzoate.

Project description:In the mol-ecule of the title compound, C(15)H(15)NO(4)S, the dihedral angle between the two rings is 88.05 (7)°. The methyl ester group is nearly coplanar with the adjacent ring [dihedral angle = 2.81 (10)°], whereas it is oriented at 86.90 (9)° with respect to the plane of the ring attached to the -SO(2)- group. Weak intra-molecular C-H⋯O hydrogen bonding completes S(5) and S(6) ring motifs. The mol-ecules form one-dimensional polymeric C(8) chains along the [010] direction due to N-H⋯O hydrogen bonding and these chains are linked by C-H⋯O hydrogen bonds, forming a three-dimensional network.
