l-Leucinium fluoride monohydrate

Abstract

The asymmetric unit of the title hydrated salt, C6H14NO2+·F−·H2O, contains a discrete cation with a protonated amino group, a halide anion and one water molecule. The crystal structure is composed of double layers parallel to (010) held together by N—H...O, N—H...F, O—H...F and C—H...F hydrogen bonds, forming a two-dimensional network, and stacked along the c axis, viz. hydrophilic layers at z = 0 and 1/2 and hydrophobic layers at z = 1/3 and 2/3.
