Crystal structure of l-tryptophan–fumaric acid–water (1/1/1)
نویسندگان
چکیده
In the title compound, C11H12N2O2·C4H4O4·H2O, the l-tryp-to-phan mol-ecule crystallized as a zwitterion, together with a neutral fumaric acid mol-ecule and a water solvent mol-ecule. In the crystal, the three components are linked by a series of N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds, forming slabs lying parallel to (001). The slabs are connected by O-H⋯O hydrogen bonds, involving inversion-related fumaric acid groups, leading to the formation of a three-dimensional structure.

The title complex, [Pr(2)(C(4)H(2)O(4))(3)(C(4)H(4)O(4))(H(2)O)(2)](n), was synthesized by reaction of praseodymium(III) nitrate hexa-hydrate with fumaric acid in a water-ethanol (4:1) solution. The asymmetric unit comprises a Pr(3+) cation, one and a half fumarate dianions (L(2-)), one half-mol-ecule of fumaric acid (H(2)L) and one coordinated water mol-ecule. The carboxyl-ate groups of the fu...

With the aim of improving the solubility of ciprofloxacin, polybasic organic acids were utilized to react with ciprofloxacin in different stoichiometric proportions. The use of the solvent drop grinding (SDG) method, as well as the solvent evaporation method, resulted in the crystalline salts ciprofloxacin/fumaric acid (1:1, 2:1), ciprofloxacin/maleic acid (1:1) and ciprofloxacin/citric acid (2...
