1-Hydroxy-ethyl-2-methyl-5-nitro-imidazolium 3-carb-oxy-4-hydroxy-benzene-sulfonate.

ABSTRACT: Cocrystallization of 1-hydroxy-ethyl-2-methyl-5-nitroimidazole (metronidazole) and 5-sulfosalicylic acid (5-H(2)SSA) from methanol solution yields the title salt, C(6)H(10)N(3)O(3) (+)·C(7)H(5)O(6)S(-). In the crystal structure, the ions are linked by a combination of inter-molecular O-H?O, N-H?O and C-H?O hydrogen bonds, forming a three-dimensional framework. The hydroxyl group of the cation is disordered over two sites in a 0.860?(4):0.140?(4) ratio.

Cocrystallization of 1-hydroxy-ethyl-2-methyl-5-nitroimidazole (metronidazole) and 5-sulfosalicylic acid (5-H(2)SSA) from methanol solution yields the title salt, C(6)H(10)N(3)O(3) (+)·C(7)H(5)O(6)S(-). In the crystal structure, the ions are linked by a combination of inter-molecular O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds, forming a three-dimensional framework. The hydroxyl group of the cation is disordered over two sites in a 0.860 (4):0.140 (4) ratio. ...[more]

Project description:The asymmetric unit of the title salt, C(6)H(9)N(2) (+)·C(7)H(5)O(6)S(-), contains two crystallographically independent 2-amino-5-methylpyridinium cations and two sulfosalicylate anions.

The ionic units are linked by N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds. Furthermore, the crystal structure is stabilized by π-π inter-actions between the benzene and pyridine rings [centroid-centroid distances = 3.5579 (8) and 3.8309 (8) Å]. There are also intra-molecular O-H⋯O hydrogen bonds in the anions, which generate S(6) ring motifs.

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.
