Crystal structure of 2-amino-4-methylpyridin-1-ium (2R,3R)-3-carboxy-2,3-dihydroxypropanoate monohydrate

Abstract

The title molecular salt, C6H9N2+·C4H5O6−·H2O, crystallized with two 2-amino-4-methylpyridin-1-ium cations, two l-(+)-tartaric acid monoanions [systematic name: (2R,3R)-3-carboxy-2,3-dihydroxypropanoate] and two water molecules in the asymmetric unit. In the crystal, the cations, anions and water molecules are linked via a number of O—H...O and N—H...O hydrogen bonds, and a C—H...O hydrogen bond, forming a three-dimensional structure
