摘要：

The title compound, C9H14N2O, exists in the zwitterionic form in the crystal. The cyclooctane ring adopts a twisted boat-chair conformation. In the crystal, intermolecular N-H center dot center dot center dot O hydrogen bonds link the molecules into sheets lying parallel to the bc plane. The structure is also stabilized by pi-pi interactions, with a centroid-to-centroid distance of 3.5684 (8) angstrom.
