Biphenylene dianion has been prepared by Li reduction of the parent hydrocarbon. It is stable below -30' and was characterized by its 'Hand I3C-NMR spectra. A comparison of these data with those of the dication indicates he existence of ion pairs in the dianion case which are responsible for a diffe
