摘要：

In the crystal, two N-acetyl-L-prolylglycinamide molecules form the asymmetric unit and are linked as a dimer by two hydrogen bonds between the N-H groups and amidic O atoms. Each molecule shares six hydrogen bonds with three translated conformers. All the hydrogen bonds lie approximately in planes, which separate the apolar regions. In both independent molecules, the puckering of the proline rings can be described as slightly distorted C2-C(beta)-exo conformations.
