Unprecedented zwitterion in quinonoid chemistry.
The first 12 pi-electron zwitterionic structure in quinonoid chemistry is described with the N,N,O,O-molecule 6 in which the positive charge is pi-delocalized between the nitrogen atoms and the negative charge between the oxygen atoms; depending on the crystallization solvent, a 1D-tape-like H-bonded network can be generated in the solid-state.
