摘要：

Slight delocalization and strategically placed double bonds have combined to make this unique ring system planar. Pairs of molecules interact across a crystallographic inversion centre to form hydrogen-bonded dimers utilizing a ketonic O atom and an adjacent amine H atom [N ... O 2.907(3), N-H 0.83(3), H ... O 2.08 (3) Angstrom; N-H ... O 172(3)degrees].
