Crystal structure of sodium (1S)-d-lyxit-1-yl-sulfonate.

ABSTRACT: The title compound, Na(+)·C5H11O8S(-) [systematic name: sodium (1S,2S,3S,4R)-1,2,3,4,5-penta-hydroxy-pentane-1-sulfonate], is formed by reaction of d-lyxose with sodium bis-ulfite (sodium hydrogen sulfite) in water. The anion has an open-chain structure in which one of the oxygen atoms of the sulfonate residue, the S atom, the C atoms of the sugar chain and the O atom of the hy-droxy-methyl group form an essentially planar zigzag chain with the corresponding torsion angles lying between 179.80?(11) and 167.74?(14)°. A three-dimensional bonding network exists in the crystal structure involving hexa-coordination of sodium ions by O atoms, three of which are provided by a single d-lyxose-sulfonate unit and the other three by two sulfonate groups and one hy-droxy-methyl group, each from separate units of the adduct. Extensive inter-molecular O-H?O hydrogen bonding supplements this bonding network.

Project description:The title compound, K(+)·C5H11O8S(-)·H2O [systematic name: potassium (1S,2S,3S,4R)-1,2,3,4,5-penta-hydroxy-pentane-1-sulfonate monohydrate], formed by reaction of d-lyxose with potassium hydrogen sulfite in water, crystallizes as colourless square prisms.

A three-dimensional bonding network exists in the crystal structure involving coordination of two crystallographically independent potassium ions by O atoms (one cation being hexa- and the other octa-coordinate, with each lying on a twofold rotation axis), and extensive inter-molecular O-H⋯O hydrogen bonding.

Crystal structure of sodium (1<i>S</i>)-d-mannit-1-yl-sulfonate.

Project description:The title salt, Na+·C6H13O9S- [systematic name: sodium (1S,2S,3S,4R,5R)-1,2,3,4,5,6-hexa-hydroxy-hexane-1-sulfonate], is formed by reaction of d-mannose with sodium bis-ulfite (sodium hydrogen sulfite) in water. The anion has an open-chain structure with the S atom and the C atoms of the carbohydrate chain forming an essentially planar zigzag chain in which the absolute values of the torsion angles lie between 173.6?(2) and 179.9?(3)°. The sodium cations are penta--coordinated by O atoms, with one link to a carbohydrate O atom and four to O atoms of sulfonate residues in separate anions, thus creating a three-dimensional network. The carbohydrate anions are arranged in a head (-SO3-) to head (-SO3-) arrangement, thereby forming two parallel sheets linked through coordination to sodium ions, with each sheet containing inter-molecular hydrogen bonds between the anionic residues. Unusually, the double sheets are not connected to neighbouring sets of double sheets, either by ion coordination or inter-molecular hydrogen bonding.

Crystal structure of tetra-methyl-tetra-thia-fulvalenium (1S)-camphor-10-sulfonate dihydrate.

Project description:Electro-oxidation of tetra-methyl-tetra-thia-fulvalene (TMTTF) in the presence of the chiral anion (1S)-camphor-10-sulfonate (S-camphSO3 (-)) in tetra-hydro-furan/water medium afforded a 1/1 salt formulated as TMTTF·S-camphSO3·2H2O or 2-(4,5-dimethyl-1,3-di-thiol-2-yl-idene)-4,5-dimethyl-1,3-di-thiole radical ion (1+) [(1S)-7,7-dimethyl-2-oxobi-cyclo-[2.2.1]heptan-1-yl]methane-sulfonate dihydrate, C10H12S4 (+)·C10H15O4S(-)·2H2O. In this salt, two independent TMTTF units are present but, in both cases, the observed bond lengths and especially the central C=C distance [1.392 (6) and 1.378 (6) Å] are in agreement with a complete oxidation of TMTTF which is thus present as TMTTF (.) (+) radical cations. These cations form one-dimensional stacks in which they are associated two by two, forming dimers with short [3.472 (1) to 3.554 (2) Å] S⋯S contacts. The two S-camphSO3 anions present also form stacks and are connected with each other via the water mol-ecules with many O-H⋯O hydrogen bonds ranging from 1.86 (3) to 2.15 (4) Å; the O-H⋯O hydrogen-bonding network can be described as being constituted of C 2 (2)(6) chains bearing R 3 (3)(11) lateral rings. On the other hand, the columns of cations and anions are connected through C-H⋯O hydrogen bonds, forming a system expanding in three directions; finally, the result is a three-dimensional network of O-H⋯O and C-H⋯O hydrogen bonds.

Crystal structure of potassium (1R)-d-ribit-1-yl-sulfonate.

Project description:The title compound, K(+)·C5H11O8S(-) [systematic name: potassium (1R,2R,3R,4R)-1,2,3,4,5-penta-hydroxy-pentane-1-sulfonate], formed by reaction of d-ribose with potassium hydrogen sulfite in water, crystallizes as colourless plates. The anion has an open-chain structure in which the S atom and the C atoms of the sugar chain, excepting that of the hy-droxy-methyl group, form an essentially all-trans chain; the C atom of the hy-droxy-methyl group lies in a gauche relationship with the three contiguous C atoms. Through complex cation coordination (through seven oxygen atoms of six different anions) and inter-molecular O-H?O hydrogen bonding, a three-dimensional bonding network exists in the crystal structure.

Sodium (1R)-d-glucit-1-yl-sulfonate monohydrate.

Project description:The title salt, Na(+)·C(6)H(13)O(9)S(-)·H(2)O, crystallizes with three independent cations, molecular anions and solvent water molecules in the asymmetric unit. This crystalline monohydrate addition product, formed by reaction of d-glucose and sodium hydrogen sulfite in water, forms a three-dimensional network through complex cation coordination and extensive inter-molecular hydrogen bonding. Each of the independent mol-ecules has an open-chain structure with the carbon chains adopting a sickle-like conformation, similar to that found in the potassium salt [Cole et al. (2001 ?). Carbohydr. Res.335, 1-10], but there are significant differences in the patterns of complexation.

Crystal structure of 3-benzamido-1-(4-nitro-benz-yl)quinolinium tri-fluoro-methane-sulfonate.

Project description:In the title compound, C23H18N3O3 (+)·CF3SO3 (-), the asymmetric unit contains two crystallographically independent organic cations with similar conformations. Each cation shows a moderate distortion between the planes of the amide groups and the quinolinium rings with dihedral angles of 14.90 (2) and 31.66 (2)°. The quinolinium and phenyl rings are slightly twisted with respect to each other at dihedral angles of 6.99 (4) and 8.54 (4)°. The tri-fluoro-methane-sulfonate anions are linked to the organic cations via N-H⋯O hydrogen-bonding inter-actions involving the NH amide groups. In the crystal, the organic cations are linked by weak C-H⋯O(nitro group) inter-actions into supramol-ecular chains propagating along the b-axis direction.

Crystal structure of zwitterionic 2-[bis-(2-meth-oxy-phen-yl)phosphanium-yl]-4-methyl-benzene-sulfonate monohydrate di-chloro-methane monosolvate.

Project description:In the title compound, C21H21O5PS·H2O·CH2Cl2, the phospho-nium-sulfonate zwitterion has the acidic H atom located on the P atom rather than the sulfonate group. The S-O bond lengths [1.4453 (15)-1.4521 (14) Å] are essentially equal. In the crystal, the water mol-ecules bridge two zwitterions via Owater-H⋯Osulfonate hydrogen bonds into a centrosymmetric dimer. The dimers are further linked by weak CAr-yl-H⋯Osulfonate hydrogen bonds into chains extending along [100]. The PH(+) group is not involved in inter-molecular inter-actions.

Project description:The title compound, C12H7Cl3O3S, was synthesized via a nucleophilic substitution reaction between phenol and 2,4,5-tri-chloro-benzene-sulfonyl chloride. The two aryl rings are oriented gauche to one another around the sulfonate S-O bond, with a C-S-O-C torsion angle of -70.68?(16)°, and the two rings are inclined to one another by 72.40?(7)°. In the crystal, mol-ecules are linked via various C-Cl?? inter-actions, forming ribbons propagating along [100]. Neighboring ribbons are linked by a weak C-Cl?? inter-action, forming layers parallel to (010).

Short intra-molecular C-H?O and C-H?Br inter-actions occur. In the crystal, the component ions are linked by inter-molecular N-H?O and C-H?O hydrogen bonds.
