Crystal structure of sodium (1S)-d-lyxit-1-ylsulfonate
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 gro...

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. The anion has an open-chain structure in which the S atom, the C atoms of the sugar chain and the oxygen atom of the hy-droxy-methyl group fo...
متن کاملCrystal structure of (1S,4S)-2,5-diazoniabicyclo[2.2.1]heptane dibromide
The cage of 2,5-di-aza-bicyclo-[2.2.1]heptane is frequently employed in synthetic chemistry as a rigid bicyclic counterpart of the piperazine ring. The 2,5-di-azabicyclo-[2.2.1]heptane scaffold is incorporated into a variety of compounds having pharmacological and catalytic applications. The unsubstituted parent ring of the system, 2,5-di-aza-bicyclo-[2.2.1]heptane itself, has not been structur...
متن کاملCrystal structure of N-[(1S,2S)-2-aminocyclohexyl]-2,4,6-trimethylbenzenesulfonamide
The title compound, C15H24N2O2S, was synthesized via a substitution reaction between the enanti-opure (1S,2S)-(+)-1,2-di-amino-cyclo-hexane and 2,4,6-tri-methyl-benzene-1-sulfonyl chloride. The cyclo-hexyl and phenyl substituents are oriented gauche around the sulfonamide S-N bond. In the crystal, mol-ecules are linked via N-H⋯N hydrogen bonds, forming chains propagating along [100].
