Crystal structure of γ-methyl l-glutamate N-carboxy anhydride

In the title compound, C7H9NO5, alternative name N-carboxy-l-glutamic anhydride γ-methyl ester, the oxazolidine ring is essentially planar with a maximum deviation of 0.020 (3) Å. In the crystal, molecules are linked by N—H...O hydrogen bonds between the imino group and the carbonyl O atom in the me...

The tapes are also stacked along the b axis with short contacts between the oxazolidine rings [C...O contact distances = 2.808 (4)–3.060 (4) Å], so that the oxazolidine rings are arranged in a layer parallel to the ab plane. This arrangement of the oxazolidine rings is very preferable for the polymerization of the title compound in the solid state.http://scripts.iucr.org/cgi-bin/paper?S2056989014026917crystal structurepolymerizationamino acid N-carboxy anhydrideshydrogen bonding
