4-{2-[(E)-Cyclo-pentyl-idene]hydrazin-1-yl}benzene-sulfonamide.

ABSTRACT: The title mol-ecule, C(11)H(15)N(3)O(2)S, features a five-membered ring which is twisted about the middle CH(2)-CH(2) bond. The benzene ring is inclined with respect to the imine residue [C-N-N-C torsion angle = 165.4?(2)°]. Supra-molecular layers in the bc plane are formed by hydrogen bonds between the amine H atoms and sulfonamide O and imine N atoms, as well as by a weak hydrazine H-atom inter-molecular inter-action with the second sulfonamide O atom.

Project description:The asymmetric unit of the title compound, C(9)H(11)ClN(4), contains two virtually planar mol-ecules that differ in conformation about the bond connecting the hydrazine and pyridazine units. The 3-chloro-6-hydrazinylpyridazine and cyclo-pentane groups are oriented at dihedral angles of 4.5?(3) and 8.8?(4)° in the two mol-ecules. In the crystal, the mol-ecules form a one dimensional polymeric structure extending along the a axis via N-H?N hydrogen bonds. The crystal stucired was an inversion twin [ratio of the twin domains = 0.73?(9):0.27?(9)].

Project description:In the title compound, C20H18BrN3S, the cyclo-pentane ring adopts a half-chair conformation.

2-(N-Cyclo-hexyl-carbamo-yl)benzene-sulfonamide.

Project description:The asymmetric unit of the title compound, C(13)H(18)N(2)O(3)S, contains two mol-ecules with similar conformations. In both mol-ecules, the cyclo-hexyl rings adopt chair conformations, with the attached N atom in an equatorial orientation and an intra-molecular N-H?O hydrogen bond generates an S(7) ring. In the crystal, N-H?O hydrogen bonds link the mol-ecules and a C-H?O hydrogen bond is also observed. The crystal studied was a racemic twin.

Crystal structure of (E)-N-{2-[2-(3-chloro-benzyl-idene)hydrazin-yl]-2-oxoeth-yl}-4-methyl-benzene-sulfonamide monohydrate.

Project description:The mol-ecule of the title compound, C16H16ClN3O3S·H2O, is L-shaped being bent at the S atom; the S-N-C-C torsion angle is 132.0 (3)°. The central part of the mol-ecule, C-C-N-N=C, is almost linear, with the C-C-N-N and C-N-N=C torsion angles being -174.1 (2) and 176.0 (2)°, respectively. The dihedral angle between the p-toluene-sulfonyl ring and the S-N-C-C(=O) segment is 67.5 (4)°, while that between the two aromatic rings is 52.17 (11)°. In the crystal, the water H atom is involved in O-H⋯O hydrogen bonds with a sulfonamide O atom and the carbonyl O atom. The water O atom is itself hydrogen bonded to both NH hydrogen atoms. These four hydrogen bonds lead to the formation of corrugated sheets lying parallel to (100). There are also weak C-H⋯O contacts present within the sheets.
