Abstract

The title compound, C11H17NO6, was prepared by the reaction of 1-aminocyclohexanecarboxylic acid with monochloroacetic acid. In the molecule one of three carboxy groups is deprotonated while the N atom is protonated, thus the molecule exists as an inner salt in the crystal structure. The crystal packing is stabilized by intermolecular O—H⋯O hydrogen bonding; an intramolecular N—H⋯O hydrogen bond is also present. [ABSTRACT FROM AUTHOR]

Abstract

A form ofdl-aspartic acid, C4H7NO4 is presented, which crystallizes in the same space group as the previously reported form but with a slightly different a axis. Its structure exhibits a three-dimensional supramolecular network of N—H...O and O—H...O bonds, which stabilizes the crystal packing. [ABSTRACT FROM AUTHOR]
