cif-access (organic compounds)
The structures of (I) and (II) were determined at 134 K. The pyrrolidine rings have similar twist conformations in both compounds. Molecules of (II) are connected through intermolecular N-HO hydrogen bonds into zigzag chains.
Both crystal structures contain weak intermolecular C-HO interactions.
Compound (II) also shows intermolecular C-Harene interactions.
