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

ABSTRACT: 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.

2,2'-(p-Phenyl-ene)bis-(4,5-dihydro-1H-imidazol-3-ium) bis-(3-nitro-benzoate).

Project description:In the title compound, C(12)H(16)N(4) (+)·2C(7)H(4)NO(4) (-), the complete 2,2'-(p-phenyl-ene)bis-(4,5-dihydro-1H-imidazol-3-ium) (bib) dication is generated by crystallographic inversion symmetry. The bib cations reside on crystallographic inversion centers, which coincide with the centroids of the respective benzene rings. In the cation, the imidazole ring adopts an envelop conformation with the flap atom displaced by 0.082?(3)?Å from the plane through the other ring atoms. In the crystal, the cations and anions are linked through inter-molecular N-H?O hydrogen bonds, forming chains running along the a axis. C-H?O inter-actions also occur. Weak ?-? contacts between the imidazole rings of bib and between the benzene rings of NB [centroid-centroid distances = 3.501?(1) and 3.281?(2)?Å, respectively] may further stabilize the structure.
