Glycine–phthalic acid (1/1) [PDF]
Acta Crystallographica Section E Structure Reports Online, 2012 In the title compound, C2H5NO2·C8H6O4, the glycine mol-ecule exists as a zwitterion (2-aza-niumyl-ethano-ate) with a positively charged amino group and a negatively charged carboxyl-ate group. In the crystal, N-H⋯O and O-H⋯O hydrogen bonds link the components into layers parallel to the ab plane.
