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

ABSTRACT: 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.

Project description:The title compound, C17H16ClN3O2·H2O, an acyl-hydrazone derivative, contains a glycine moiety and two substituted benzene rings on either end of the chain. It crystallized as a monohydrate. The mol-ecules adopt an E conformation with respect to the C=N double bond, as indicated by the N-N=C-C torsion angle of 179.38 (14)°. The mol-ecule is twisted in such a way that the almost planar Car-C(=O)-N(H)-C(H2) and C(H2)-C(=O)N(H)-N=C-Car [r.m.s deviations = 0.009 and 0.025 Å, respectively] segments are inclined to on another by 77.36 (8)°, while the benzene rings are normal to one another, making a dihedral angle of 89.69 (9)°. In the crystal, the water mol-ecule links three mol-ecules through two O-H⋯O and one N-H⋯O hydrogen bonds. The mol-ecules are linked via pairs of N-H⋯O hydrogen bonds, forming inversion dimers with an R 2 (2)(14) ring motif. The dimers are linked by O-H⋯O hydrogen bonds, involving two mol-ecules of water, forming chains along [100], enclosing R 2 (2)(14) and R 2 (2)(18) ring motifs. The chains are linked through C-H⋯O inter-actions, forming sheets parallel to (010). Within the sheets, there are C-H⋯π and parallel slipped π-π stacking inter-actions present [inter-centroid distance = 3.6458 (12) Å].

Crystal structure of (E)-N-{2-[2-(4-methyl-benzyl-idene)hydrazin-1-yl]-2-oxoeth-yl}-p-toluene-sulfonamide.

Project description:The title acyl-hydrazone derivative, C17H19N3O3S, containing an amino acid moiety and electron-donating substituents attached to both the phenyl rings, crystallized with two independent mol-ecules (A and B) in the asymmetric unit. The mol-ecules are bent at the S atom, with C-SO2-NH-CH2 torsion angles of -67.3 (2) and 67.7 (3)° in mol-ecules A and B, respectively. Further, the dihedral angles between the sulfonyl-glycine segments and the p-toluene-sulfonyl rings are 76.1 (1) and 85.8 (1)° in mol-ecules A and B, respectively. The central hydrazone segments and the toluene rings attached to them are almost co-planar with their mean planes being inclined to one another by 5.2 (2) (mol-ecule A) and 2.9 (2)° (mol-ecule B). The dihedral angles between the benzene rings are 86.83 (12) (mol-ecule A) and 74.00 (14)° (mol-ecule B). In the crystal, the A mol-ecules are linked by a pair of N-H⋯O hydrogen bonds, forming inversion dimers with an R 2 (2)(8) ring motif. The dimers are linked via three N-H⋯O hydrogen bonds involving the B mol-ecules, forming chains along [100] and enclosing R 2 (2)(12) and R 4 (4)(16) ring motifs. The chains are linked via C-H⋯O hydrogen bonds and a C-H⋯π inter-action, forming sheets parallel to (010). There is a further C-H⋯π inter-action and a slipped parallel π-π inter-action [inter-centroid distance = 3.8773 (16) Å] between the sheets, leading to the formation of a three-dimensional framework.

7-Chloro-4-[(E)-N'-(4-fluoro-benzyl-idene)hydrazin-yl]quinoline monohydrate.

Project description:The mol-ecule of the title hydrate, C(16)H(11)ClFN(3)·H(2)O, is slightly twisted, as indicated by the dihedral angle of 9.55?(10)° formed between the quinoline ring system and the benzene ring. The conformation about the C=N double bond is E, and the amine-H atom is oriented towards the quinoline residue. In the crystal structure, the water mol-ecule accepts an N-H?O and makes two O-H?N(quinoline) hydrogen bonds, generating a two-dimensional array in the ab plane, which is further stabilized by C-H?O inter-actions. The most significant contacts between layers are of the type C-H?F.

4-{2-[(5-Chloro-2-hydroxy-benzyl-idene)amino]eth-yl}benzene-sulfonamide.

Project description:In the mol-ecule of the title compound, C(15)H(15)ClN(2)O(3)S, the S atom adopts a distorted tetra-hedral coordination geometry with two O atoms, one N atom of the amide group and one C atom of the aromatic ring. An intra-molecular O-H⋯N hydrogen bond results in the formation of a planar six-membered ring, which is oriented with respect to the adjacent aromatic ring at a dihedral angle of 3.38 (11)°. Thus, the two rings are nearly coplanar. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers.

Crystal structure of (E)-4-methyl-N-{2-[2-(4-nitro-benzyl-idene)hydrazin-1-yl]-2-oxoeth-yl}benzene-sulfonamide N,N-di-methyl-formamide monosolvate.

Project description:The mol-ecule of the title Schiff base compound, C16H16N4O5S·C3H7NO, displays a trans conformation with respect to the C=N double bond. The C-N and N-N bonds are relatively short compared to their normal bond lengths, indicating some degree of delocalization in the mol-ecule. The mol-ecule is bent at the S atom, with an S-N-C-C torsion angle of 164.48 (11)°. The dihedral angle between the two aromatic rings is 84.594 (7)°. Inter-molecular N-H⋯O and C -H⋯O hydrogen bonds connect centrosymmetrically related mol-ecules into dimers forming rings of R33(11) and R22(10) graph-set motif stacked along the a axis into a columnar arrangement. The mol-ecular columns are further linked into a three-dimensional network by C-H⋯π inter-actions.

Crystal structure and Hirshfeld surface analysis of (E)-4-chloro-N-{2-[2-(4-nitro-benzyl-idene)hydrazin-1-yl]-2-oxoeth-yl}benzene-sulfonamide N,N-di-methyl-formamide monosolvate.

Project description:The asymmetric unit of the title compound, C15H13ClN4O5S·C3H7NO, contains one mol-ecule each of the Schiff base and the solvent di-methyl-formamide. The hydrazone group adopts an E configuration about the C=N bond. The dihedral angle between the two aromatic rings is 86.58?(2)°. In the crystal, pairs of N-H?O hydrogen bonds between centrosymmetrically related mol-ecules generates rings with an R22(10) graph-set motif. The dimers are further linked via N-H?O and C-H?O hydrogen bonds, leading to the formation of R33(11) ring motifs. C-H?? inter-actions are also observed. The inter-molecular inter-actions in the crystal structure were qu-anti-fied and analysed using Hirshfeld surface analysis, which indicates that the most significant contacts in packing are O?H/H?O (31.3%), followed by H?H (25.4%) and C?H/H?C (13.0%).
