摘要
In the title compound, C(25)H(20)Br(2)N(2)(2+)center dot 2NO(3)(-), the cation lies on a twofold rotation axis which imposes disorder of the dibromofluorene unit. In addition, the unique nitrate anion is disordered over two general sites of equal occupancy. The crystal structure is stabilized by intermolecular N-H center dot center dot center dot O hydrogen bonds.
