Benzyltributylammonium 4-hydroxynaphthalene-2-sulfonate
The title compound, C(19)H(34)N(+)·C(10)H(7)O(4)S(-), is a charge-control agent used for toners in electrophotography. In the crystal structure, centrosymmetric anions associate through O-H⋯O hydrogen bonds formed between the O-H group of one anion and the sulfonate O atom of a neighbor. The components of the dimer are offset with respect to each other so that the separation between the two par...

In the title compound, C(15)H(14)F(2)O(3)S, the dihedral angle between the aromatic rings is 6.19 (13)°. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds, generating [110] chains.
متن کاملCrystal structure of diethylammonium aniline-4-sulfonate anilinium-4-sulfonate
The title compound, C4H12N+·C6H6NO3S-·C6H7NO3S, consists of an ion pair and a zwitterionic neutral mol-ecule. The cation adopts an extended conformation [C-C-N-C torsion angles = 177.1 (3) and -178.4 (3)°]. In the crystal, the components are linked by N-H⋯O and N-H⋯N hydrogen bonds, generating a three-dimensional network, which is consolidated by weak C-H⋯O inter-actions.
متن کامل4-(4-Aminophenylsulfonyl)anilinium toluene-4-sulfonate
In the title p-toluene-sulfonate salt of the drug dapsone, C12H13N2O2S(+)·C7H7O3S(-), the dihedral angle between the two aromatic rings of the dapsone monocation is 70.19 (17)° and those between these rings and that of the p-toluene-sulfonate anion are 72.34 (17) and 46.43 (17)°. All amine and aminium H atoms are involved in inter-molecular N-H⋯O hydrogen-bonding associations with sulfonyl O-at...
متن کامل4-Hydroxypyridinium-3-sulfonate
The reaction of 4-hy-droxy-pyridine and oleum produces 4-hy-droxy-pyridinium-3-sulfonate, C(5)H(5)NO(4)S, which shows delocalized bonds in the six-membered ring. In the crystal, adjacent zwitterions are linked by N-H⋯O and O-H⋯O hydrogen bonds into a layer motif. The crystal studied was a racemic twin.
