N,N-Bis(2-oxopyr rolidin-l-ylmeth yl)glycine

The molecular structure of the title compound, CI2HI9N304, shows that the three moieties attached to the central, neutral N atom are each nearly planar. The molecules are linked by O---H...O hydrogen bonds between the COOH group and one of the pyrrolidone groups of an adjacent molecule, and C--H..-O hydrogen bonds between one methylene of another pyrrolidone group and the C==O of the same pyrrolidone group of an adjacent molecule.
