Piperazine-1,4-diium (R)-2-[4-(1-carboxylatomethoxy)phenoxy]propanoate

Abstract

In the anion of the title molecular salt, C4H12N22+·C11H10O62−, the two acetate groups form torsion angles of 74.1 (1) and 7.1 (1)° with the central benzene ring, and the cation exhibits a chair conformation. In the crystal, N—H...O hydrogen bonds link the components into a two-dimensional supramolecular network lying parallel to the ab plane. A number of C—H...O interactions consolidate the packing.
