In both ionic components of the title salt, C(4)H(7)N(2) (+)·C(6)H(2)N(3)O(7) (-), the rings are approximately planar; the maximum deviation from the mean plane is an order of magnitude larger in the picrate ring [0.0289 (10) Å] than in the imidazolium ring [0.0028 (10) Å. The nitro groups are twisted with respect to the six-atom ring plane; the NO(2) groups next to the oxide O atom, at the 2- and 6-positions, are twisted more [by 53.59 (9) and 18.46 (12)°] than the NO(2) group at the 4-postitio ...[more]
