Figure 2
An ellipsoid plot (50% probability) showing the mol­ecular structure of 2AcAP·HCl. Unlabeled atoms are related to their labeled counterparts by a crystallographic twofold rotation (−x + 1, y, −z + [{1\over 2}]). The unusually short N—H⋯N hydrogen bond between the pyrrolizidine N atoms is highlighted by open dashed lines. Weaker N—H⋯Cl hydrogen bonds between the acetamide NH group and the Cl anion are shown as dotted lines.
