2-Methylimidazolium picrate [PDF]

Acta Crystallographica Section E Structure Reports Online, 2010
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.

3-Aminopyridinium picrate [PDF]

Acta Crystallographica Section E Structure Reports Online, 2010
During the formation of the title compound, C(5)H(7)N(2) (+)·C(6)H(2)N(3)O(7) (-), a phenolic proton is transferred to the pyridine N atom. In the crystal structure, the ions are linked by inter-molecular N-H⋯O and N-H⋯(O,O) hydrogen bonds into layers running parallel to (100).
