3,3'-(p-Phenyl-enedimethyl-ene)di-1H-imidazol-1-ium bis-(4-nitro-benzoate)-4-nitro-benzoic acid (1/2)



3,3'-(p-Phenyl-enedimethyl-ene)di-1H-imidazol-1-ium bis-(4-nitro-benzoate)-4-nitro-benzoic acid (1/2)



Acta Crystallographica. Section E Structure Reports Online 66(Pt 6): O1485



The asymmetric unit of the title compound, C(14)H(16)N(4) (2+)·2C(7)H(4)NO(4) (-)·2C(7)H(5)NO(4), comprises one-half of the 3,3'-(p-phenyl-enedimethyl-ene)di-1H-imidazol-1-ium dication, which lies on an inversion centre, one 4-nitro-benzoate anion and one 4-nitro-benzoic acid mol-ecule. In the crystal, the components are linked into a two-dimensional network parallel to (110) by O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds.
