Hydronium 4-oxo-1,4-dihydropyridine-3-sulfonate dihydrate
2-Hydroxy-pyridine when treated with concentrated sulfuric acid is sulfonated at the 3-position to yield the title hydrated salt, H(3)O(+)·C(5)H(4)NO(3)S(-)·2H(2)O. In the crystal structure, the cations, anions and uncoordinated water mol-ecules are linked by extensive O-H⋯O and N-H⋯O hydrogen bonds into a three-dimensional network. The crystal studied is a non-merohedral twin with a twin compo...
متن کاملPotassium (1R,4R,5S,8S)-4,5,8-trihydroxy-3-oxo-2,6-dioxabicyclo[3.3.0]octane-4-sulfonate dihydrate
The title salt, K(+)·C6H7O9S(-)·2H2O, formed by reaction of dehydro-l-ascorbic acid with potassium hydrogen sulfite in water, crystallizes as colourless plates. The potassium ion is coordinated by eight O atoms arising from hy-droxy or sulfonate groups. The sulfonate group is bonded to the C atom neighbouring that of the lactone carbonyl group. As is commonly observed in crystalline l-ascorbic ...
متن کامل3-Aminopyridinium 4-hydroxy-3-iodonaphthalene-1-sulfonate dihydrate
In the hydrated title salt, C(5)H(7)N(2) (+)·C(10)H(6)IO(4)S(-)·2H(2)O, the component species are linked by O-H⋯O and N-H⋯O hydrogen bonds, forming an infinite three-dimensional framework.
متن کامل4,4′-Bipyridinium bis(μ-4-oxo-1,4-dihydropyridine-2,6-dicarboxylato)bis[aquahydroxidoantimonate(III)] dihydrate
The title compound, (C(10)H(10)N(2))[Sb(2)(C(7)H(2)NO(5))(2)(OH)(2)(H(2)O)(2)]·2H(2)O, consists of a binuclear anion, a diprotonated 4,4'-bipyridinium cation and two uncoordinated water mol-ecules. Each Sb(III) atom is six-coordinated by one chelating 4-oxidopyridine-2,6-dicarboxyl-ate ligand, one water mol-ecule, one OH group and one bridging O atom from a neighboring carboxyl-ate group in a d...
متن کامل2-Methyl-3-(2-methylphenyl)-4-oxo-3,4-dihydroquinazolin-8-yl 4-bromobenzene-1-sulfonate
The title mol-ecule, C(22)H(17)BrN(2)O(4)S, has a twisted U shape, the dihedral angle between the quinazolin-4-one and bromo-benzene ring systems being 46.25 (8)°. In order to avoid steric clashes with adjacent substituents on the quinazolin-4-one ring, the N-bound tolyl group occupies an orthogonal position [dihedral angle = 89.59 (8)°]. In the crystal, mol-ecules are connected into a three-di...
