[Norbornane skeleton] Displacement ellipsoids drawn at 50% probability level. H atoms are omitted for a clearer view of the norbornane skeleton.
A derivative of triazanorbornane has been synthesized and is the first such compound to be fully characterized by X-ray crystallographic analysis. The six-membered diaza ring is in a chair conformation but the bridging aza atom produces ring strain. Despite this, the structure is completely stable due to anomeric interactions in the N—C—N groups.
