ABSTRACT: In the title compound, C13H13BrO4S, both C=C double bonds adopt an E conformation. The S atom has a distorted tetra-hedral geometry with bond angles ranging from 102.17?(13) to 119.77?(14)°. The ethyl acrylate substituent adopts an extented conformation with all torsion angles close to 180°. In the crystal, mol-ecules are linked into centrosymmetric R 2 (2)(14) dimers via pairs of C-H?O hydrogen bonds.

2,3-Diamino-pyridinium (2E,4E)-hexa-2,4-dienoate.

Project description:In the title salt, C(5)H(8)N(3) (+)·C(6)H(7)O(2) (-), the pyridine N atom of the 2,3-diamino-pyridine mol-ecule is protonated. The 2,3-diamino-pyridinium cation is essentially planar, with a maximum deviation of 0.068 (2) Å for one of the amino N atoms. The sorbate anion adopts an extended conformation. In the crystal structure, the protonated N atom and one of the two amino-group H atoms are hydrogen bonded to the sorbate anion through a pair of N-H⋯O hydrogen bonds, forming an R(2) (2)(8) ring motif. The ion pairs are further connected via inter-molecular N-H⋯O and C-H⋯O hydrogen bonds, forming two-dimensional networks parallel to (100).

Project description:In the title compound, C(27)H(20)ClNO, the quinoline ring forms a dihedral angle of 62.53?(5)° with the substituent benzene ring.

Inter-molecular C-H?N and C-H?O hydrogen bonds further consolidate the structure into a three-dimensional network. The unit cell contains four solvent-accessible voids, each with a volume of 35?Å(3), but no significant electron density was found in them.

(2E)-2-(2,4-Dichloro-phenyl-sulfon-yl)-3-(3-methoxy-anilino)-3-(methyl-sulfan-yl)acrylonitrile.

Project description:The title compound, C(17)H(14)Cl(2)N(2)O(3)S(2), and the 4-methyl-anilino analogue reported in the following paper have been used as starting materials to develop benzothia-zine derivatives with anti-malarial activity. The mol-ecule displays an E (trans) configuration about the central double bond. Due to conjugation in the C=C-C N group, the putative single bond shows a significant shortening [1.421 (3) Å]. The mol-ecule has a six-membered ring involving an intra-molecular N-H⋯O(sulfon-yl) bond, which is an example of resonance-assisted hydrogen bonding. There is also an intra-molecular N-H⋯Cl hydrogen bond. In the crystal structure, bonds of the C-H⋯O(sulfon-yl) type form chains that run along [101], while N-H⋯O(sulfon-yl) bonds connect centrosymmetrically related molecules in pairs of these chains, forming ribbons. Comparison of the N⋯O distances in the intra- and inter-molecular N-H⋯O(sulfon-yl) bonds reveals that the π-bond co-operativity results in a strengthening of the intra-molecular hydrogen bond. There are also π-π inter-actions between benzene rings of pairs of centrosymmetrically related mol-ecules [centroid-centroid distance = 3.8612 (13) Å], as well as C-H⋯π interactions.

(2E)-2-(2,4-Dichloro-phenyl-sulfon-yl)-3-(4-methyl-anilino)-3-(methyl-sulfan-yl)acrylonitrile.

Project description:The title compound, C(17)H(14)Cl(2)N(2)O(2)S(2), and the 3-methoxy-anilino analogue reported in the preceding paper have been used as starting materials to develop benzothia-zine derivatives with anti-malarial activity. The mol-ecule displays an E (trans) configuration about the central double bond. Due to conjugation in the C=C-C N group, the putative single bond shows a significant shortening [1.418 (3) Å]. The mol-ecule has a six-membered ring involving an intra-molecular N-H⋯O(sulfon-yl) bond, which is an example of resonance-assisted hydrogen bonding. In the crystal structure, bonds of the C-H⋯O(sulfon-yl) and C-H⋯N(cyano) types form double layers of mol-ecules parallel to (01). Within these layers there are π-π inter-actions between benzene rings of pairs of centrosymmetrically related mol-ecules, with distances of 3.7969 (12) Å between centroids. C-H⋯π interactions are also present.
