2-Amino-1H-benzoimidazol-3-ium 4,4,4-trifluoro-1,3-dioxo-1-phenyl-butan-2-ide.

ABSTRACT

In the title compound, C(7)H(8)N(3) (+)·C(10)H(6)F(3)O(2) (-), 1H-benzoimidazol-2-amine system adopts a planar conformation with an r.m.s. deviation of 0.0174 Å. The cation and anion in the asymmetric unit are linked by N-H⋯O hydrogen bonds. There are also additional inter-molecular N-H⋯O hydrogen bonds and π-π stacking inter-actions between the phenyl rings of neighbouring anions with centroid-centroid distances of 4.0976 (13) Å.
