Abstract
In the title compound, C 5 H 14 NO + .C 4 H 5 O 6 - .H 2 O, the hydrogen-bond system created by the chains of head-to-tail linked hydrogen tartrate ions and water molecules forms a V-shaped layer that is effective in discriminating between the two enantiomers of protonated 2-amino-3-methyl-1-butanol. The cation adopts a conformation that isolates its hydrophilic and hydrophobic parts, which is common for other cations containing the same N-C-C-O fragment.
