用N,N,O,O-分子6描述了喹酮类化学中的第一个12电子两性离子结构,其中正电荷在氮原子之间离域,负电荷在氧原子之间离域;根据结晶溶剂的不同,在固体中可以产生一维带状氢键网络。
The first 12-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.
