Glycinium 3-carb-oxy-4-hy-droxy-benzene-sulfonate.

ABSTRACT: In the anion of the title salt, C2H6NO2 (+)·C7H5O6S(-), the dihedral angle between the carb-oxy-lic acid group and the benzene ring is 5.02?(12)°. In the crystal, the anions are linked into inversion dimers through pairs of O-H?O hydrogen bonds between the carb-oxy-lic acid groups and sulfonate O atoms. A pair of C-H?O inter-actions is also observed within each dimer. The anion dimers and the cations are linked into a three-dimensional network by N-H?O, O-H?O and C-H?O hydrogen bonds.

In the anion of the title salt, C2H6NO2 (+)·C7H5O6S(-), the dihedral angle between the carb-oxy-lic acid group and the benzene ring is 5.02 (12)°. In the crystal, the anions are linked into inversion dimers through pairs of O-H⋯O hydrogen bonds between the carb-oxy-lic acid groups and sulfonate O atoms. A pair of C-H⋯O inter-actions is also observed within each dimer. The anion dimers and the cations are linked into a three-dimensional network by N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds. ...[more]

Project description:In the crystal structure of the title compound, [Mg(H(2)O)(6)](C(7)H(5)O(6)S)(2)·2H(2)O, the octa-hedral complex cation lies on an inversion centre and is hydrogen bonded through the coordinated water molecules to the substituted benzene-sulfonate monoanions and the water mol-ecules of solvation.

Project description:The asymmetric unit of the title salt, C(5)H(6)ClN(2) (+)·C(7)H(5)O(6)S(-), contains two independent 2-amino-5-chloro-pyridinium cations and two independent 3-carb-oxy-4-hy-droxy-benzene-sulfonate anions.

In each anion, an intra-molecular O-H⋯O hydrogen bond generating an S(6) motif is observed. In the crystal structure, the cations and anions are linked via N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds, forming a two-dimensional network parallel to (110).

The crystal studied was a non-merohedral twin, with a ratio of the twin components of 0.715 (3):0.285 (3).

2-Amino-4-methyl-pyridinium 3-carb-oxy-4-hy-droxy-benzene-sulfonate monohydrate.

Project description:In the crystal structure of the title salt, C(6)H(9)N(2) (+)·C(7)H(5)O(6)S(-)·H(2)O, the water mol-ecule acts as an acceptor of bifurcated N-H?O hydrogen bonds from the pyridinium H atom and one H atom of the 2-amino group, forming an R(2) (1)(6) ring. The 3-carb-oxy-4-hy-droxy-benzene-sulfonate anions self-assemble via O-H?O hydrogen bonds, leading to supra-molecular chains along the a axis. These chains and R(2) (1)(6) motifs are linked via O-H?O, N-H?O and C-H?O hydrogen bonds, forming a layer parallel to the ac plane. There is also an intra-molecular O-H?O hydrogen bond in the 3-carb-oxy-4-hy-droxy-benzene-sulfonate anion, generating an S(6) ring motif.
