Methyl 3-O-?-d-mannopyranosyl ?-d-glucopyran-oside tetra-hydrate.

ABSTRACT: The title compound, C(13)H(24)O(11)·4H(2)O, forms extended hydrogen-bonded networks. These are present between disaccharides, but not as inter-residue hydrogen bonds, as well as to water mol-ecules that in addition form an inter-molecular chain of hydrogen bonds. The conformation of the disaccharide is described by the glycosidic torsion angles ?(H) = -34° and ?(H) = -5°. Macroscopically, the disaccharide was observed to be hygroscopic.

The title compound, C(13)H(24)O(11)·4H(2)O, forms extended hydrogen-bonded networks. These are present between disaccharides, but not as inter-residue hydrogen bonds, as well as to water mol-ecules that in addition form an inter-molecular chain of hydrogen bonds. The conformation of the disaccharide is described by the glycosidic torsion angles ϕ(H) = -34° and ψ(H) = -5°. Macroscopically, the disaccharide was observed to be hygroscopic. ...[more]

Methyl 3-O-?-l-fucopyranosyl ?-d-glucopyran-oside tetra-hydrate.

Project description:The title compound, C(13)H(24)O(10)·4H(2)O, is the methyl glycoside of a disaccharide structural element present in the backbone of the capsular polysaccharide from Klebsiella K1, which contains only three sugars and a substituent in the polysaccharide repeating unit. The conformation of the title disaccharide is described by the glycosidic torsion angles ?(H) = 51.1?(1)° and ?(H) = 25.8?(1)°. In the crystal, a number of O-H?O hydrogen bonds link the methyl glycoside and water mol-ecules, forming a three-dimensional network. One water mol-ecule is disordered over two positions with occupancies of 0.748?(4) and 0.252?(4).

2,2,5,7,8-Penta-methyl-chroman-6-yl 2,3,4,6-tetra-O-acetyl-α-d-glucopyran-oside from synchrotron data.

Project description:The crystal structure of the title compound, C(28)H(38)O(11), solved and refined against synchrotron diffraction data, contains two formula units in the asymmetric unit. In both mol-ecules, the dihydro-pyran ring along with its methyl substituents is disordered and adopts two alternative half-chair conformations. The occupancy of the major conformers of the two mol-ecules refined to 0.858 (5) and 0.523 (5).

2,3,4,6-Tetra-O-acetyl-2-phthalimido-?-d-glucopyran-oside.

Project description:In the crystal structure of the title compound, C(24)H(27)NO(11), a substituted tetra-acetyl glucopyran-oside derivative, weak inter-molecular C-H?O hydrogen bonds link the mol-ecules into ribbons propagated in [010]. The d configuration has been attributed on the basis of the synthesis and the ? anomer has been determined from the structure.

3,4-Dicyano-phenyl 2,3,4,6-tetra-O-acetyl-?-d-glucopyran-oside.

Project description:The title compound, C(22)H(22)N(2)O(10), was prepared by the glycosidation method through nitrite displacement on substituted nitro-phthalonitrile. The mol-ecule contains a benzene ring, two nitrile groups and an acetyl-protected d-glucose fragment which adopts a chair conformation. The absolute configuration was determined by the use of d-glucose as starting material. All substituents of the protected sugar are in equatorial positions, with the exclusive presence of the ?-anomer. The crystal packing is stabilized by C-H?O and C-H?N hydrogen-bonding inter-actions.

5,10,15,20-Tetra-kis(1-methyl-pyridinium-4-yl)porphyrin tetra-iodide tetra-hydrate.

Project description:The asymmetric unit of the title compound, C(44)H(38)N(8) (2+)·4I(-)·4H(2)O, comprises two halves of non-equivalent cations of 5,10,15,20-tetra-kis-(1-methyl-pyridinium)porphyrin (with the full mol-ecule of each completed by the application of inversion symmetry), four charge balancing iodide anions and four water mol-ecules of crystallization (two water mol-ecules are fully occupied and four mol-ecules have a site occupancy of 50%). The porphyrin cations are arranged into supramolecular columns parallel to the b axis, mediated by π-π [centroid-centroid distance = 3.762 (4) Å] and C-H⋯π supra-molecular inter-actions [C⋯centroid distance = 3.522 (7) Å, C-H⋯centroid = 128°], leading to the formation of columns parallel to the b axis. The close packing leads to the presence of a one-dimensional channel filled with partially occupied water mol-ecules engaged in O-H⋯O and O-H⋯I hydrogen bonds.
